Tokyo-to isn't a real place, but for anyone who owned a Dreamcast in the year 2000, it felt more alive than the city outside their window. You probably remember the feeling of grinding down a 50-foot handrail while a distorted voice screamed about "Extra Sugar! Extra Salt! Extra Oil and MSG!" into your headset. It was chaotic. It was loud. Honestly, it was kind of a miracle that it worked at all. The Jet Set Radio original soundtrack didn't just provide background noise for a game about graffiti-tagging inline skaters; it essentially invented a new aesthetic that people are still trying to copy twenty-five years later.
If you look at the music landscape of the late nineties, everything was siloed. You had your rock, your hip-hop, and your burgeoning electronic scene. Then Hideki Naganuma walked in. He didn't care about genres. He cared about energy.
The Man Behind the Concept of Love
Hideki Naganuma is the name you need to know if you want to understand why this music hits different. Before he became a cult hero on Twitter for his eccentric posts, he was a composer at Sega who was tasked with creating something "street." But "street" is a dangerous word in corporate meetings; it usually leads to watered-down, cringey imitations of whatever is on the radio. Naganuma avoided that trap by leaning into "sampling" as a primary instrument.
He used the Roland SP-808 GrooveSampler like a weapon. By chopping up funk riffs, disco loops, and nonsensical vocal snippets, he created a soundscape that felt like flipping through a hundred radio stations at once while riding a rollercoaster. Tracks like "Humming the Bassline" and "Let Mom Sleep" aren't just songs. They are collages.
Why sampling was the secret sauce
Most game soundtracks back then were MIDI-based or symphonic. Naganuma went the other way. He took the "cut-and-paste" ethos of Beastie Boys’ Paul’s Boutique or The Dust Brothers and applied it to a medium that usually relied on looping melodies. When you hear that iconic "Check it out, what's up guys" at the start of a level, it’s not just a voice line. It’s a rhythmic anchor. It grounds the player in the world of Professor K and the GGs.
The Jet Set Radio original soundtrack wasn't just Naganuma, though. It was a global effort. Sega brought in external talent like Guitarader, Deavid Soul, and even Rob Zombie (for the North American "Jet Grind Radio" release). This mix of Japanese "Future Funk" and Western Big Beat gave the game a weird, universal appeal. It felt like it belonged to everyone and no one at the same time.

Breaking Down the Genre-Defying Tracklist
Let's get into the weeds. You’ve got "Super Brothers," which sounds like a 70s heist movie being remixed by a DJ in a neon-lit basement. Then you have "Miller Ball Breakers," a track so aggressive it makes you want to spray-paint your own living room. The variety is staggering.
One of the most misunderstood things about this soundtrack is that people often call it "J-Pop." It’s really not. There are elements of acid jazz, breakbeat, trip-hop, and even funk-rock. It’s "Sampling Music" in its purest form. Take a song like "Rock It On." It starts with a simple, driving beat and then layers in these high-pitched synth stabs that mimic the sound of a spray can rattling. That’s not an accident. That’s intentional sound design masquerading as a pop song.
It’s about the "groove."
In an interview with Red Bull Music Academy, Naganuma once mentioned that he didn't really look at other video games for inspiration. He looked at the club scene. He looked at what people were dancing to in Shibuya. That’s why the music feels so physical. When the beat drops in "Sneakman," you don't just hear it; you feel the momentum of the character on screen.
The regional differences (and why they matter)
When the game traveled from Japan to the US and Europe, the tracklist shifted.

- The Japanese Release: Pure Naganuma and Deavid Soul vibes.
- The US Version (Jet Grind Radio): Added Jurassic 5 and Rob Zombie.
- The PAL Version: Included tracks like "On the Run."
Purists will argue until they are blue in the face about which version is superior. Some say the addition of "Dragula" by Rob Zombie ruined the "street" vibe of the original. Others argue that Jurassic 5’s "Improvise" fit the graffiti culture perfectly. Honestly? They both work. The game's engine was built on the idea of a "pirate radio station," and what is a radio station if not a chaotic mix of different voices?
The "Jet Set" Legacy in Modern Gaming
We wouldn't be talking about the Jet Set Radio original soundtrack if its influence died with the Dreamcast. But it didn't. You can see its DNA in everything from Persona 5 (which uses heavy acid jazz influences) to Splatoon. Specifically, Splatoon owes its entire identity to Jet Set Radio. The "Squid Sisters" and "Off the Hook" tracks use that same "gibberish vocal as an instrument" technique that Naganuma perfected.
Then there is Bomb Rush Cyberfunk. Released in 2023 by Team Reptile, it was a spiritual successor that did the one thing it had to do to be successful: it hired Hideki Naganuma.
Hearing "DA PEOPLE" or "GET ENUF" in a modern game felt like a homecoming. It proved that this specific brand of high-tempo, sample-heavy funk isn't just a nostalgic relic. It’s a viable musical language.
Technical Mastery with Limited Hardware
You have to remember that the Dreamcast was powerful, but it still had limits. Audio compression was a real issue. Naganuma had to fit these high-quality samples into a very small memory footprint. This is probably why the music sounds so "crunchy." That lo-fi grit wasn't necessarily a stylistic choice at first—it was a necessity. But like many great pieces of art, the limitations defined the style. That slight distortion on the vocals? It made it feel like you were actually listening to a bootleg radio broadcast.

It’s raw.
Music today is often too clean. Too perfect. The Jet Set Radio original soundtrack is messy. It’s got "mistakes" that are left in because they sound cool. It captures a specific moment in the late 90s/early 2000s where the internet was just starting to connect us, and we were all obsessed with what the "future" would look like. Turns out, the future sounded like a funky bassline and a man shouting about "The Concept of Love."
How to Experience the OST Today
If you’re looking to dive back in, don't just look for a generic "Greatest Hits" playlist. To really get the effect, you need to listen to the full, unedited versions of the tracks.
- Seek out the 2012 Remaster: When Sega ported the game to HD platforms, they cleaned up some of the audio tracks. While some of the licensed music (like "Recipe for the Perfect Afro") has occasionally faced licensing hurdles, most of the Naganuma classics are there in high fidelity.
- Vinyl is King: If you can find the Data Discs vinyl release, grab it. The artwork alone is worth it, but hearing these tracks on an analog format highlights the "warmth" of the original samples.
- The "Set It Off" Fan Project: There is a massive community of fans who have tracked down every single original sample Naganuma used—from old 70s funk records to obscure Japanese commercials. Finding these "source" tracks is a rabbit hole worth falling down.
The Jet Set Radio original soundtrack is more than just a collection of songs. It’s a mood. It’s a reminder that games can be more than just "content"—they can be a cohesive artistic statement where the music, the art style, and the gameplay are all vibrating on the same frequency.
Actionable Next Steps
If you want to truly appreciate the craftsmanship here, start by listening to "Humming the Bassline" through a good pair of headphones. Pay attention to how many different sounds are layered on top of each other. Then, look up the Bomb Rush Cyberfunk soundtrack to see how that sound has evolved for the modern era. If you’re a creator, take a page out of Naganuma’s book: don't worry about what’s "standard" in your industry. Find a weird sample, loop it, and see where it takes you. The world always has room for more "Extra Sugar, Extra Salt."
