Eminem has done some decent stuff as have a lot of modern artists,I don't buy it myself but my daughter changed my view on rap.Despite the content and language most these days deliver a positive message.A recent phenomena she pointed out to me was how many of them start out really negative then the better their "product" becomes the more positive it gets,might be a brain thing.Take the fun yt clip I posted above, that boy goes to school with my grandson and has gone from quiet boy to school celeb.This could get him to learn an instrument/mix whatever. What you don't want is someone coming in too soon and showing him all that's wrong with it.Wrong handling or snobbery could push him away from a potential passion/career.As peoples ears are educated their taste changes,stuff I was passionate about in my teens is only of nostalgic value now.
      Just tried to think of a genre/style where I could say yes never heard anything from that sphere that was any good,but I couldn't.
