>>10Rush is freaking awesome. Happy Bivouac is without a doubt my favorite album of theirs, but man they have some great ones. Please Mr. Lostman, Little Busters, and Runner's High are probably the other really solid ones.
I'd say check out Little Busters next, you'd probably really dig the opening track, "Welcome to Bubbletown's Happy Zoo (Instant Show)". There's another song on their though called "Nowhere" that has probably my favorite subject / lyrics of theirs. Definitely won't disappoint.
