It’s not an uncommon occurrence to see pop stars work with video game companies on soundtracks and in-game appearances. However, some folks rose a curious eye when former Beatle Paul McCartney teamed up with former composer Marty O’Donnell and the team at Bungie to work on the soundtrack for Activision’s forthcoming space epic Destiny.

However, it looks like the compilation will pay off for both parties. McCartney, who helped produce the score for the game alongside O’Donnell (before he was dismissed), will be releasing a song based around the game for the public on September 9 – the same day that the game releases.

Recorded with a 120-piece orchestra, the song revolves around the theme of hope, and utilized the classic Abbey Road studio to gather that McCartney vibe, so it sounded just right, according to The New York Times.

McCartney has been working with Bungie on the project for ten years, expressing his gratitude for taking part in a tweet from 2012. “I’m really excited to be working on writing music with @bungie, the studio that made Halo,” he said.

The soundtrack, which also features the work of Mike Salvatori, will include a large 50-minute suite, along with McCartney’s song and other melodies.

McCartney’s involvement in the project shows the devotion that Activision is putting behind it, with a rumored $500 million budget that includes marketing and production. So far, it’s paid off, as the game has earned record numbers between its two betas, and has a high number of pre-orders, the largest that any new IP has seen to date.
