Can anyone suggest any good songs/ artist?

I just want to listen to some deep music. I don't want just angry, often unintelligiable screaming. I just want something that makes me think, and can make me happy or sad or anything besides rowdy and wanting to break stuff.
I already listen to Three days grace, a perfect circle, disturbed, linkin park, Apocalyptica, and all sorts of other bands, but i doubt i'm really aware of most other bands. If you can tell me any good artists and songs by them, that would be most helpful.
