I've found a problem with the genius playlists, which only seems to happen on the iPhone and not in iTunes. When I choose the song for the playlist to be based on, if I were to choose any of the songs from Yero Zero R3M1X3D by NIN it always plays the song from the original Year Zero album. I can't really see why it is doing this, as the track titles aren't the same, for example Capital G on the original album and on the remix album it is Capital G [Epworth Phones Remix] and obviously the album title is different. Is anyone else having the same problem? Does anyone know how I could sort this out?
