if this ain't in Sonic 4 I ain't watching

I remember thinking this was a mashup of it doesn't matter and the sonic heroes theme my first time hearing lol x)

Sonic Songa

Team Sonic Theme Sonic heroes

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.
