Agreed about new hip-hop although there's some exceptions. One guy I've been listening to lately is XV. I like his stuff and he's under the radar. It seems like once rappers hit the mainstream they sell out to the fame and money. I use to like Lil Wayne back in the old days before he exploded with this whole Young Money and rock experimentation crap. Same is going to happen to Drake, don't know why he signed with Young Money. Right now hip-hop actually has some hope compared to the past, lots of young blood. J. Cole, XV, Cudi, and Big Sean are just a few. There's also Jay Electronica, Charles Hamilton, Joell Ortiz, etc. I think you might like an artist called Blu. Check him out.
