This is just my opinion but: I hoestly don't consider any vocalist a legit artist unless they write some very profound original stuff, or play an instrument. I see it like this, all a vocalist is doing is talking/shouting in a way that is often pleasing to the ear. I mean, ANYONE could do that if given the right genetics, with the exception of opera singers that push thier voices to the limit. I don't consider anything art if it's just a matter of genetics, so a singer is as much an artist as a model. What do you think?
