hip hop.
Nas (illmatic and Stillmatic only)
common, mos def, blackalicious, last emperor, pharoah monch, dilated peoples, nappy roots, aesop rock, aceyalone, binary star, so many good groups that don't get heard.
i tend to listen to music for lyrical pleasure. it has to have great flow or developed thought/content. i recently discovered i listen to music more for the lyrics than the music itself.
