I've done a bit of googling on this the last couple of days but can't find an answer... I have recently subscribed to Match, in order to be able to access and organise my music on different computers. One of my primary ways of organising my music is using smart playlists, but these don't seem to work properly on my iPhone since turning Match on. Tracks don't show up in the correct order and there are loads of duplicates. There doesn't seem to be any logic or pattern to the way it's messed up. Does anyone know what might be causing it? Is there a particular definition in the Smart playlists that causes the problems?
