Mario Kart World's Jazz-Fusion Soundtrack Finally Arrives on Nintendo Music - Alongside the Service's Biggest Update Yet

The Soundtrack That Deserved an Award (But Got Shredded Instead)

When Polygon declared Mario Kart World’s soundtrack “the best game soundtrack of 2025,” it wasn’t just a throwaway line. The publication devoted an entire feature to explaining why composer Atsuko Asahi’s live big-band arrangements of classic Mario themes stood head and shoulders above the orchestral scores that dominated that year — including Clair Obscur: Expedition 33, Death Stranding 2, and Ghost of Yōtei. Where those soundtracks aimed for cinematic grandeur, Asahi and her team went for visceral energy, recruiting members of legendary Japanese jazz-fusion bands Dezolve and T-Square alongside 13 other session musicians to perform the tracks live in studio.

The result is a sound that is unmistakably Mario Kart yet unlike anything the series has produced before. The brass sections punch, the saxophones wail, and the rhythm section drives with a swagger that makes even a Rainbow Road remix feel like a night at a smoky jazz club. It’s a continuation of the formula Mario Kart 8 pioneered in 2014, but elevated by the raw energy of a full live ensemble.

Despite near-universal critical acclaim and being the most-requested addition to Nintendo Music’s library — per IGN’s reporting — the soundtrack received zero nominations at any major game awards in 2025. Speculation among observers suggests it may have been overlooked because it didn’t fit the “cinematic” mold that awards voters tend to favor. The snub only deepened the soundtrack’s cult status among fans, who rallied around it as proof that playful, inventive music deserves the same recognition as sweeping orchestral epics.

Today, that status becomes official. The Mario Kart World soundtrack on Nintendo Music contains 130 tracks totaling 4 hours and 13 minutes of music — not the 37 tracks some initial reports claimed, which was likely a batch error. The full library of race and event music is now available. Free Roam and open-world exploration tracks are not yet included, but Nintendo has confirmed they will arrive in a future update, according to multiple authoritative sources including VGC, Vooks, and Nintenderos.

Nintendo Music’s Biggest Update Yet – Web, Car, Tablet

If the soundtrack addition is the headline, the accompanying Version 1.6.0 update is the story beneath it. For the first time since Nintendo Music launched in October 2024 exclusively on iOS and Android for Nintendo Switch Online subscribers, the service is breaking out of mobile. The update introduces a web player accessible at music.nintendo.com, which allows listeners to preview a selection of tracks even without an active subscription. For full access, you still need a Switch Online membership, but the barrier to entry has lowered significantly.

Beyond the web, native apps have landed on iPad, Apple CarPlay, and Android Auto. For anyone who has ever wanted to blast the Mario Kart World soundtrack during a road trip or while working at a desk, this is a major quality-of-life improvement. The update also adds Siri-based track search and a “My Mix” playlist feature for personalized listening, bringing Nintendo Music closer to the feature set of competing streaming services.

The timing of this update is no accident. It coincides with the Switch 2’s first anniversary on June 5 and a newly announced Mario Kart World hardware bundle. By positioning the soundtrack’s arrival alongside this platform expansion, Nintendo is signaling that music is a core part of its new ecosystem — not an afterthought.

What’s On the Service (And What’s Missing)

For those diving into the soundtrack today, the full racing lineup is present. All 130 tracks cover every race course, battle arena, and event mode from the base game. Highlights include the blistering live arrangement of “Mario Circuit” (featuring a trumpet solo that rivals anything from a Buddy Rich album) and a surprisingly melancholic take on “Rainbow Road” that pairs lush strings with a driving brass line.

What you won’t find yet is the Free Roam music — the ambient, exploration-oriented tracks that play while driving through Mario Kart World’s open world outside of races. Nintendo has explicitly stated these will be added in a future update, but no timeline has been given. For now, the service includes the full race and battle library, leaving only the Free Roam material absent. It’s a small gap in an otherwise complete library, and one that fans have already begun requesting.

The track count discrepancy that confused some outlets earlier this week is now resolved. The 130-track figure is confirmed by Nintendo Life, Polygon, IGN, VGC, and NME, aligning with the 4-hour-plus runtime. The earlier 37-track claim appears to have been an initial batch or a reporting error.

What This Means for Nintendo’s Music Strategy

Nintendo Music has now added over 130 game soundtracks in less than two years, but Mario Kart World is the first Switch 2-era score to join the service. That’s a deliberate choice. By prioritizing its flagship new release, Nintendo is signaling that the service will serve as a companion to marquee hardware launches, not just a nostalgia library.

The platform expansion — web, car, tablet — removes friction for subscribers and opens the door to potential free-tier expansion or even a standalone subscription option down the line. For now, the web player’s preview feature is a taste, but it’s easy to imagine Nintendo testing a limited free tier in the future.

Perhaps most importantly, by spotlighting a jazz-fusion soundtrack over the orchestral “prestige” scores that usually win awards, Nintendo reinforces its brand identity: playful, inventive, and unafraid to go against industry trends. The Mario Kart World soundtrack isn’t trying to be a cinematic score. It’s trying to make you smile while you drift around a corner at 200 km/h. And in an industry obsessed with gravitas, that’s a quiet act of rebellion.

The Wait is Over – and the Free Roam Tracks Are Next

The arrival of Mario Kart World’s soundtrack on Nintendo Music is more than a belated addition. It’s a celebration of one of 2025’s most original game scores, finally accessible outside the console. Combined with the service’s biggest update, Nintendo is signaling that game music belongs everywhere — from the car to the desk to the living room. For fans who have been waiting nearly a year to hear those live sax solos on repeat, the wait is over. And with Free Roam tracks confirmed for a future update, the soundtrack’s journey is only beginning to unfold.
