LOL really though - hiphop is a good form of music as far as how it sounds (not what it says).
Unfortunately white people are still better at it, which is why freestyle battle championships goto white people 9 out of 10 times.

The record-label side of the rap industry has locked out white rappers, its an extremely racist industry.
If too many white rappers get signed to major labels it would raise the standards for lyrical content - something most black rappers are incapable of with their lack of education and limited vocabulary.
So for the time-being, if you like the sound of rap you're stuck listening to some dumb black guy rhyme over it, at least on the radio and MTV.
