i studied alot of theory growing up... i was in the same boat as you. the music i loved just didn't mean anything anymore!
one thing i did which helped was getting a healthy dose of really simple music. like, trance or early beatles or green day or, in a way, P-Funk. (not always the simplest thing, P-Funk.... but there's such an importance placed on pure groove.)
also, the person who said something about listening to the rhyhmic elements more.... that's kinda like where i'm going with all this. i just listen to music that concentrates mostly on rhythm, along with the crazy weird stuff i'm also into. like penderecki, or john cage.
listen to P-Funk. it'll help, if you can dig it.
