Breaking Benjamin.

Those are some songs.
I'm a fanboy since discovering So Cold, I can't tell why. They're nothing that special, but I just like their conventional, yet not mainstreamish style, I like Ben's voice and also Chad Szeliga is a great drummer.
I got my girlfriend hooked to them too and she actually likes their harder songs better (e.g. Wish I May or Breakdown over Rain or Forever) being the only girl not thinking exactely the other way around. I love her <3.
Listen to some of their stuff if you like Postgrunge and Alt.Rock/Metal.
