Re: HIP HOP
There's some great hip-hop music. But unless you seek it out, you've probably not heard a lot of it. Hip-hop is like any other musical genre in that you can't judge it by only listening to the hits. The stuff that gets airplay doesn't represent the best of hip-hop any more than top-40 represents the best of rock music.
I do think it's kind of funny when drummers cite the absence of melody as the reason they don't like hip-hop. :)
