If you’ve ever found yourself deep in a rabbit hole of experimental trap at 2 AM, chances are 645AR has already found you. Born Austin Alan Rochez on September 2, 1997 in the South Bronx and now based in Atlanta, Georgia, this rapper has carved out one of the most genuinely bizarre and thrillingly original niches in modern hip-hop. His weapon? A naturally high-pitched, squeaky falsetto that sounds like a human synthesizer pushed beyond its operating limits — except it’s completely real. No pitch correction. Just an artist who’s pushed his voice into a sonic dimension most rappers wouldn’t dare explore.
From the moment his 2018 single “Crack” got reposted by Lil Tecca and broke the internet, 645AR has been on a mission to redefine what rap can sound like. His discography spans gritty trap bangers, hyperpop-adjacent experiments, pluggnb grooves, and emotionally raw reflections — all filtered through that unmistakable squeak. Whether you’re a longtime fan or just discovering him for the first time, this collection of his 20 best songs is your definitive starting point. These are real, verified tracks from his catalog, pulled from projects including Most Hated (2025), IN DAT MODE (2024), Space AR Star (2024), The Bambino (2024), comfort noise (2022), Most Hated (2021), No Label (2020), and his 2019 self-titled debut.

4 Da Trap
Released in 2019 as a single and later featured on the Most Hated (2021) EP, “4 Da Trap” is the track that made the world sit up and take notice of 645AR. The production — a sparse, clanking trap beat with eerie, minimalist synth layers — is the perfect canvas for his voice to operate at peak strangeness. What strikes you most is how committed he is to the delivery. There’s no hedging, no moment where it sounds like he’s holding back. The squeaky vocals don’t just sit on top of the beat; they become the beat’s emotional spine. It spread so rapidly on Twitter that the platform actually suspended his account, mistaking his virality for spam. That kind of cultural disruption doesn’t happen by accident — it happens when art is genuinely unprecedented.
Sum Bout U (feat. FKA twigs)
This 2020 collaboration with FKA twigs is arguably the most important song in 645AR’s discography in terms of legitimizing his artistry to a broader audience. The two artists occupy completely different corners of experimental music, yet somehow their energies collapse into something extraordinary. FKA twigs brings her ethereal, breathy R&B delivery while 645AR layers his high-pitched squeaks beneath and around her vocals, creating a genuinely alien sonic texture. The production leans atmospheric and melancholy, with a sparse beat that gives both artists room to breathe. Released on August 4, 2020, this single received coverage across major music publications and proved that 645AR wasn’t just a meme — he was a legitimate collaborator capable of holding his own with one of music’s most critically acclaimed voices.
Bible And A K
Originally released in 2019 and part of his self-titled debut, “Bible And A K” is historically significant because it was one of the first songs where 645AR fully committed to his now-iconic squeak delivery. The track has a raw, unpolished energy that feels authentic to his South Bronx roots — hard, street-rooted lyricism wrapped in a voice that sounds like it belongs to another dimension. The contrast between the subject matter and the delivery is what makes it so compelling. Apple Music notes it as a distinctive squeaky flow milestone, and listeners who have been following since 2019 often cite this as the origin point of the 645AR sound. On headphones, the spatial production is especially effective, with hi-hats that feel like they’re panning right past your ears.
YOGA
From his 2020 output, “YOGA” demonstrates the range within 645AR’s trap framework. The beat has a bouncy, almost playful quality that makes it one of his more accessible entry points while still being unmistakably him. What works so well here is the rhythmic interplay between his vocal phrasing and the percussion — he rides the groove like someone who has completely internalized where every snare and hi-hat lands. “YOGA” doesn’t try to be his weirdest or most experimental track; it just aims to be undeniably good, and it hits that mark. This is the kind of song that works equally well on a playlist and blasting through car speakers with the windows down.
In Dat Mode
The title track from his 2024 album IN DAT MODE sets the entire project’s tone in the most direct way possible. The production is grimier and more assertive than some of his earlier material, with bass that hits hard and a snare pattern that keeps you locked in. “In Dat Mode” feels like a mission statement — 645AR reminding listeners that no matter how experimental things get, he can still rap with intensity and purpose. The vocals have an edge that feels earned across years of building his craft, and the mix here is noticeably tighter and more polished than his 2021 work. It’s a track that rewards repeat listens, with subtle production details that reveal themselves only after you’ve had it in rotation for a while.
Jackie
Released as a single in April 2024, “Jackie” showcases a more melodic side of 645AR that has been quietly developing in his music. The beat is smoother, with a warmer low-end and cleaner arrangement than his rawer trap efforts. His vocal delivery adapts to match — still uniquely his, but with a romantic, emotionally present quality that makes it feel genuinely vulnerable. It’s the kind of track that earns its place in the category of best songs worth discovering precisely because it expands what listeners think 645AR is capable of. “Jackie” hints at what happens when squeak rap meets soulful storytelling, and it’s a compelling direction.
Whoa Vicky (feat. JWitDaBeam, 3AG Pilot)
From his 2019 era, “Whoa Vicky” is one of those tracks that has genuine replay value rooted in pure chaotic energy. Featuring JWitDaBeam and 3AG Pilot, the song has a bouncy, frantic quality that captures the reckless fun of early 645AR before the major label deal and wider spotlight. The chemistry between the collaborators is natural, with each voice adding a different texture to the mix. It’s high-energy, a little unhinged, and completely entertaining — which is exactly what it set out to be. Longtime fans often point to this era as the purest expression of the underground 645AR before the algorithm got ahold of him.
Ride 4 You
Released in 2020 as a single, “Ride 4 You” strips back some of the chaotic energy in favor of something with more emotional weight. The production here feels personal — a beat with a reflective, slower groove that allows the vocals to carry more lyrical meaning than some of his more frenetic tracks. There’s a loyalty theme running through the song that resonates genuinely rather than feeling like a generic rap trope. It’s proof that 645AR can work effectively within a more introspective mode, and it’s one of those songs that hits differently depending on where you are in life when you first hear it. This is the 645AR track to play on a long drive alone.
Crash Out
“Crash Out” from the 2021 Most Hated EP represents the raw, uncompromising side of 645AR’s trap output. The production is aggressive and lean, and the vocals are delivered with a kind of reckless urgency that matches the title’s energy perfectly. It’s one of the tracks on that project that reviewers pointed to as a highlight — the kind of song that makes you understand why the experimental vocal approach isn’t just a gimmick but an actual expressive tool. When the squeak is weaponized for intensity rather than novelty, tracks like “Crash Out” are what you get. It’s confrontational, energetic, and built for high volumes.
Sosa
From the Shishi Plugg era in 2020, “Sosa” brings a pluggnb-adjacent quality that sets it apart from straight trap cuts. The instrumental leans atmospheric, with a moodier, more nocturnal production style that suits the vocal delivery in a uniquely effective way. If you’ve ever wondered what 645AR sounds like when the production pulls back and lets the voice do more of the atmospheric heavy lifting, this track is your answer. It has a late-night energy that’s ideal for headphone listening — the kind of song that sounds completely different at midnight than it does at noon. The way the vocals float over the beat here is genuinely impressive.
In Love With A Stripper
Released in 2020 as a single, “In Love With A Stripper” takes a familiar trap subject and delivers it with 645AR’s signature voice in a way that makes it feel weirdly sincere. The production is club-ready without being generic — there’s a menace to the beat that keeps it from being purely fun, and his vocal approach adds an almost ironic sincerity to the narrative. It’s one of his most-referenced solo singles from that era, and it earns that status by being genuinely memorable rather than just provocative. The melodic hook is sticky, the delivery is committed, and the production leaves room for the vocals to shine.
Get Thru
From the 2025 Most Hated album, “Get Thru” represents a mature, focused energy in 645AR’s recent work. The production on this project is noticeably more polished than his 2021 output, and “Get Thru” benefits from tighter mixing and a cleaner sonic palette. There’s perseverance woven into the track’s DNA — it feels like a song written by someone who has navigated real obstacles and come out the other side with perspective rather than bitterness. His vocal performance adapts beautifully to the emotional register, and the result is one of the more genuinely moving moments in his 2025 catalog.
Rich Off Pain
Also from Most Hated (2025), “Rich Off Pain” channels the ambition and hunger that has always been central to 645AR’s narrative. The beat is hard-hitting with a cinematic quality — production that sounds expensive and intentional. The title functions as both a personal motto and a thesis statement for the project. His delivery here is one of the most focused and assured of the album, which makes it feel like a career highlight that he’s been building toward. Released as a single in March 2025, it showcases an artist who has refined his craft over several years without abandoning what made him interesting in the first place.
Wanna B Me
“Wanna B Me” from the 2024 IN DAT MODE project has an effortless, cool confidence to it that makes it one of the project’s most replayable moments. The production is smooth and layered, with a bass-heavy groove that anchors the track while his voice floats above it in characteristic fashion. The lyrical theme of having a unique lane that others admire but can’t replicate is entirely appropriate for an artist whose sound is genuinely inimitable — nobody else sounds like 645AR, and “Wanna B Me” leans into that with comfortable self-assurance. It’s a flex track that actually earns its flexing.
check1
From the comfort noise (2022) EP, which was released through the hyperpop imprint associated with PC Music, “check1” is one of 645AR’s most experimental recordings. The production leans into electronic textures and noise elements that push his sound closer to the hyperpop genre while still retaining his trap sensibilities. For listeners curious about where his music intersects with the avant-garde electronic scene — which has consistently drawn comparisons between 645AR and artists like 100 gecs and Dorian Electra — this track is essential listening. It’s challenging in the best possible way, the kind of song that rewards open ears. If you want the full picture, investing in good gear matters too; checking out a headphone comparison guide can help you appreciate these production details more fully.
Bag
Released in 2022, “Bag” is a focused, direct hustler track that strips the concept down to its essentials. The production is lean and punchy, with a trap groove that keeps the energy elevated throughout. “Bag” works because it doesn’t overcomplicate what it’s trying to do — it’s a song about grinding, delivered with intensity and clarity. His vocal approach fits the subject matter well, adding an urgency that straight-voiced deliveries often can’t achieve. This is the 645AR track that works best on gym playlists or late-night studio sessions, a constant-forward-motion energy that keeps you locked in.
Pick A Side
“Pick A Side” from IN DAT MODE (2024) is one of the most lyrically pointed moments on that project. There’s a directness to the track that functions almost as a confrontational statement — a demand for clarity from people in his orbit. The production matches the energy with a harder, more aggressive beat that gives the vocals an urgency they wear well. It’s one of those songs where the emotional content and the sonic packaging are genuinely aligned, creating a cohesive piece rather than a collection of disconnected elements. Among the 2024 material, this stands out as a song with real conviction behind it.
Right Or Wrong
From the 2019 Lonely At The Top project, “Right Or Wrong” has an introspective quality that feels like a window into the artist’s internal world during his earliest period of wider recognition. The production is darker and more atmospheric than his straight trap material, and his vocal delivery adapts to match — slower, more deliberate, with a weight to each phrase. It’s the kind of track that reminds you how young he was when he started attracting serious attention, and the emotional complexity here suggests an artist processing what it means to be on the rise while still feeling the weight of where he came from. For earbud listeners, pairing this with a quality set can reveal spatial production details worth exploring — a solid earbud comparison might help you find the right fit.
Shot 4 Shot
“Shot 4 Shot” encapsulates the competitive, hungry energy that runs through 645AR’s work when he’s in purist rap mode. The title implies a back-and-forth — an exchange where he’s matching anyone in the room and coming out ahead. The production is aggressive but controlled, and his voice delivers the content with a precision that makes the delivery feel genuinely threatening in the best musical sense. It’s a track that lives in the tradition of competitive rap while being delivered in a way that literally no one else could replicate. Every replay reveals another layer of conviction baked into the performance.
All By Myself
Closing out this list with a track from Space AR Star (2024), “All By Myself” has an emotional resonance that makes it a quietly powerful ending to any 645AR playlist. The title immediately signals something more introspective, and the production backs that up with a more stripped-down, atmospheric arrangement. His vocal performance here is among the most emotionally exposed in his catalog — the squeak becomes an instrument of genuine feeling rather than sonic novelty. It’s a reminder that beneath all the experimental weirdness and trap energy, there’s an artist processing real human experiences through a genuinely original artistic lens. A beautiful, melancholy piece to sit with.
