that's cool but Sonic Unleashed always wins

This song sounds like it’s from the 80s

open-your-heart Sonic Adventure

It Doesn't Matter

It came from the game Shadow The Hedgehog.

SONIC BOOM
SONIC BOOM
SONIC BOOOOOOOOOOOOOOOOOOOOOOM

These themes are all from Sonic Heroes. 4 from the teams, 1 is the main theme, and the other from a secret.
