i agree with you in the sense of the "idol" thing.. so much of it is image. however, i'm not sure you're fair to people who "just" sing. Some people are vocalists, just like some are guitar players. I don't think that's really fair not to call them real musicians. Most good vocalists write there own stuff. Some don't, some just have a great voice and charisma, imo, they certainly qualify as genuine musicians though. just like a guitar or keyboard or drums player would.
