worship Crush 40 here.

I like what I have heard of them so far, anyone recommend any good songs by them, that are not from a Sonic game?

nope. all their best songs are sonic themes. just the way it is.

if you don't like listening to sonic themes, just consider them as songs by crush 40.

 

 

and of course, the best:

Ah no, I do like the themes from the Games, just that I would have thought they actually had other songs, possibly albums away from the Sonic franchise.

 

Open Your Heart is probably my favourite, for nostalgia reasons, that and the guitar riffs are great. Awesome band =)
