I agree with most of your post, especially what you said about each artist. The thing I didn't agree with was what I quoted... Just trying to spark some debate see what everyone else thinks.
So yeah. The point of music is to showcase talent? Sure most people can appreciate talent, but I wouldn't go so far as to say it is the point of music. Music is a form of expression, a form of art and creativity; the point being to get accross a feeling, create an atmoshphere, evoke sentiments, portray ideas, etc. It is the universal language. The better you are at speaking a language the easier it is to express yourself. I feel talent has the same relationship with music. The more talented you are the easier it is to express yourself. But people less talented can still create something just as provocative.
I'm all for talent, just saying it is not a defining factor when determining whether music is good or not.
