Staind - excellent lead singer and low low guitar
Chevelle (alt metal-ish... sorta)
Three Days Grace (I like their old stuff a little better)
Boston - old
Bush - pure awesome
The Cars - old, kinda loopy synth-tastic 80's-ish
Crossfade - solid new rock
The Eagles - c'mon man...
Evans Blue -a little like breaking benjamin, sorta
Flyleaf - female lead singer, interesting band
Foo Fighters - speaks for itself
Helmet - maybe a little too heavy for your tastes?
Hurt - classical influences make for a very full sound, lead singer is extremely emotional
Incubus - I guess. lol
Nine Inch Nails - industrial
Filter - there are a couple good songs by them
Thousand Foot Krutch - kinda unknown except for a few songs, worth a listen though
Shinedown - good southern rock
And that's all I could come up with for now, sorry.
