List of Singers or Musicians who have appeared in movies?

I'm interested to see which singers or musicians have made cameos or starring roles in movies for example Anthony Kledis from Red Hot Chilli Peppers was in Point Break as a Surfie thug, and Flea was in Back to the Future Part II & III. Of course there are the obvious ones from the old era like Elvis, Sinatra and Sammy Davis Jnr but throw me your picks please, cheers...
