I'd agree with that on Kanye. I've listened to his music, but never saw the appeal, especially as time has passed ... He's more about self-absorbtion than anything else. As good as he is as, any artist is, there's a limit that what they can do - remember Micheal Jordan playing baseball? There are very few true polymaths - artists, like any other person, have limits.
For fun - The late actor Christopher Lee actually made a metal Christmas album ... (But then several metal artists have).
