Nanner, from what I hear in other posts, you and I have similar tastes in a lot of music. But I'd urge you not to turn away from hip-hop categorically. I don't like using the term "rap" because most people like to put a "c" in front. If you want smart lyrics, try this on for size.

From "The Love Song" by K-Os

Lyrical optometrists with 20/20 vision
Are serving rounds like my granny used to serve provisions
Chaotical amneotical fluid
The rap druid is fluent in the art of onomatopoeia
Metaphysical microscopic topic dropper
When I was a kid I wanted rollerskates and a bike chopper
But alas, pop, pop never thought to keep me in style
Thats why I'm schizophrenic now
So God bless the child that has his own
The harvest we reap is what we sow
Chrome microphone - shoot it
Towards a dome of computer digital clones that mimic philosopher stones
Sayin a style's their own when they bite like Mike Furounsville
The sounds ill
Relationship is a mirror
That you see yourself up in and the picture is clearer
Thats why I'm on the scene with a mike like Ernesto Guevara
Why I may exploit with lights like Geraldo Rivera, they just.
