I'm quite picky about it. I don't really like rap that much in general, but aside from nu metal and similar stuff which is not true rap. I admire the early stuff from when it was first coming out, such as stuff from Run D.M.C.
A friend is trying to get me into some of that Juggalo type stuff, although I can't see myself buying it anytime soon, I actually like some of it. A lot of violence if not more than the regular rap stuff, but the sound itself is quite catchy.
I did just get the The Dirty Heads album, Any Port In A Storm, and it's awesome. Got some reggae stuff mixed in.
