Help! iTunes library – if I want to look at my library organised by artist I get multiple entries for certain artists – it seems to that certain albums/tracks as being by different artist even though I’ve tried just copying and pasting the artist name to avoid any silly mistakes re spacing etc – for does it seem to have anything to dos with file type, genre or anything else I can think of. It works fine under the other hearings, it’s just under ‘artist’ it goes crazy – and when I want to browse by artist through the Apple TV certain albums don’t show up at all. It is infuriating. can anyone help?
