Today marks the release of Sonic Origins, a new compilation of four classic 16-bit Sonic games. One of them, Sonic The Hedgehog 3, features an altered soundtrack. Longstanding rumors suggest an uncredited Michael Jackson worked on the soundtrack for that game, composing the music for certain levels with keyboardist Brad Buxer — rumors that intensified when it became clear some of the music for Sonic 3 had been swapped out for Sonic Origins, presumably because Jackson’s estate made it hard for Sega to secure the rights to his compositions. On Twitter today, a source with knowledge of the situation confirmed that Jackson did indeed contribute music to the game.
