Artists who are the majority would get the bulk of their songs piled up at the end of the shuffle. Artists who are the minority would have always have their one or two songs showing up near the beginning of the shuffle.
 In other words: If I make it through an entire shuffle of my player (not likely) I'll be treated to a Rush-a-thon at the end. I can live with that!
