Well, I'll tell you about the Music Player, at any rate. I spent all day yesterday trying to get it to realize that every song on the Slingshot Hip-Hop album was on the same album. I even tried changing the meta-data of each track so that the artist was "See PC for artist info". No dice.
It worked fine in every other mp3 playing environment. Finally, I just auto-tagged everything except the track name to an album chosen at random, and it worked! So now I'm listening to Madonna's "Palestine, the Challenge is Ours!".
Please note that a) Palestine, the Challenge is Ours is about twelve times awesomer than most of Madonna's music, and b) if Madonna actually covered it, my head would explode.
