I do a lot of talking here about lyrics. But that's mostly because I don't know enough to discuss hip-hop, musically. Still it's worth noting that very often--especially with the Skinny Boys--I just liked the sound. It's also why I shy away from hardcore judgments about today's scene. Aesthetics in art change. There's no reason to expect them not to.
