Well, obviously it's highly possible you won't find ANY rap you like...some people just can't get into any of it...However, if you are basing your opinion of rap on what you hear on the radio, well rap has much more to offer than that.
The list Bloop just gave is a great start...For creative, different-sounding hip hop, I would definitely recommend Blackalicious-Blazing Arrow. Also, one of my personal favorites is A Tribe Called Quest..."Midnight Marauders" or "Low End Theory" would be two I would recommend there...Andree and TRu know even more about hip hop than I do, and could probably help as well...
I gave this link in the Jars of Clay thread, but I would be interested to see what you thought of this hip hop band...
