Music is a medium and playing is a craft. Some people play to express themselves in artistic ways and others play to make a living. It's all music, even when it's not art.

Nobody hates the guy who paints walls for a living for not being Picasso, but when it comes to music, everyone looks at any guy with a guitar expecting him to be the next artistic genius.

Sometimes he's just there to play three chords, get paid and go home.

I don't really like Nickelback's music, but if I ever need a house painted, I'd call them before calling someone who hasn't "sold out". I think that's their appeal.
