Yuji Naka, co-creator of Sonic the Hedgehog and producer of some early Sonic titles, obviously joined Sonic’s birthday celebrations if his Twitter account is any indication.

The former producer appears to have picked up a copy of Sonic Origins today, the compilation game that contains all four classic Mega Drive Sonic titles. Naka worked as a programmer on Sonic the Hedgehog and Sonic the Hedgehog 2, before becoming a producer (and programmer) on Sonic the Hedgehog 3 and Sonic & Knuckles. But, as many of us have already discovered, Naka is surprised to discover that the music in Sonic 3 has changed.

This reaction on Twitter exploded, as this is the producer claiming that Michael Jackson did in fact contribute music to the title in 1994.

Although this has been a hotly debated topic over the years, MJ’s collaborator Brad Buxer recently confirmed that the King of Pop helped contribute music to the game. But this hasn’t stopped the amused reactions from fans and industry insiders to Naka’s seemingly very honest reaction.

Well, there you have it then. Thus, Yuji Naka says it out loud.

If you have yet to pick up Sonic Origins or listen to the new music tracks, we’ve got you covered. The original tracks from the Mega Drive/Genesis versions have been replaced with arrangements of the prototype music, and you can listen to some of them below.
