MADEIN Music Coming to Sonic Racing: CrossWorlds as 143 Entertainment Expands SEGA Partnership

The MADEIN and Sonic Racing: CrossWorlds collaboration is apparently only getting started.

143 Entertainment has announced a new strategic partnership with SEGA and esports digital platform GAKU, confirming that MADEIN’s music will be incorporated into Sonic Racing: CrossWorlds. The announcement significantly expands a collaboration that began publicly last month, when SEGA and CrossWorlds served as official partners for MADEIN’s Link Up 2026 concert in Japan.

Sonic City covered that original partnership in July, when the collaboration was promoted directly under the MADEIN × SEGA Sonic Racing: CrossWorlds banner, complete with Sonic, Amy, Tails, and Knuckles appearing alongside the group in its promotional artwork. At the time, the announcement promised special collaboration surprises surrounding the concert, but there was no indication that MADEIN’s music was actually heading into the game itself.

Now we know the relationship goes considerably further.

According to 143 Entertainment’s August 20 announcement, SEGA has decided to include MADEIN’s music as part of its Sonic racing project, following the successful concert collaboration. Korean coverage shortens the project name to “SEGA Sonic Racing,” but given that the partnership immediately preceding this announcement was explicitly with Sonic Racing: CrossWorlds, complete with CrossWorlds branding, this is clearly the next stage of that same collaboration.

Exactly what form MADEIN’s music will take inside CrossWorlds has not yet been detailed. 143 Entertainment has not announced which song or songs will be included, whether the group is recording something specifically for the game, or when the music will arrive. CrossWorlds already has an extensive and steadily expanding Jukebox, however, with SEGA continuing to add music through updates, DLC and collaborations, so there is certainly plenty of room for MADEIN to join the soundtrack.

The new music announcement follows MADEIN’s recent Link Up 2026 concert, where SEGA participated as an official partner. According to 143 Entertainment, the concert sold out all 6,000 seats, and the company now describes that event as the beginning of the relationship between the two sides.

The partnership itself is also broader than one K-pop group appearing in one Sonic game. 143 Entertainment, SEGA and GAKU are establishing an ongoing strategic relationship built around games, music and digital entertainment, with 143 Entertainment saying the companies intend to continue pursuing global collaborations that combine those areas. GAKU is also expected to support MADEIN’s future activities through the partnership.

“We will continue various global collaborations combining games, music and digital content.”

For Sonic fans, though, the immediate takeaway is much simpler: what initially looked like a fun CrossWorlds concert tie-in has now become an actual in-game music collaboration.

Considering how aggressively Sonic Racing: CrossWorlds has been expanding its musical identity through crossover tracks, Vocaloid collaborations and its ever-growing Jukebox, MADEIN joining the playlist feels considerably less random now than it might have a month ago.

The only question left is what we are going to be racing to.
