TECHNICALLY, the Sonic 3 soundtrack is NOT stolen. Michael Jackson was originally the music producer but he was kicked at the last moment for his trouble in the child sexual harassment cases.
I was completely shocked by that Parappa one... My life is a lie!
A couple I've noticed: Part of Rock's Theme from Garou: Mark Of The Wolves sounds a hell of a lot like "Children" by Robert Miles, and The Noisettes chorus of "Don't Upset The Rhythm" sounds a bit like Sonic 2's Boss Theme
My mum just told me something rather fascinating.
Route 101 from Pokemon Red/Blue sounds almost EXACTLY like Polly Wolly Doodle. There's anotehr lil song thieving.
I agree that all of these sound similar, but I'm still having a hard time hearing the similarities between Your Name, Please and that Monty Python track. They sound completely different to me...
