Yes, most rap is dreadful, trite rubbish which has NOTHING to do with music or talent - it's largely a CHEAT. Can any of them actually play an instrument?
Of much more importance, however are 1)that it sings the praises of a vile attitude towards the rest of the world, giving young people a dreadfully wrong view of reality and 2) it has subverted black music into a travesty of what it was thirty years ago and should still be - namely the very basis of the best popular music. There are simply NO good black artists around now, they are either sneering, foul-mouthed men or appaling, warbling women churning out the most banal, valueless songs to a public increasingly fed what the major labels what them to hear. It is a shame that young black kids have no-one better to look up to than 50 cent or Missy Elliott.
