Hi, In iTunes 9, I have a playlist folder containing several similar smart playlists. Each smart playlist filters tracks on the same album title for instance "My Album", but different disc number (disc 1 to 6). Originally, these tracks were part of a series of CD's. So, they all share the same album title, but the disc number is different. Using the smart playlists, I try to group the tracks again as they were on the original CD's (hence, the filter on disc number). That works fine. Likewise, the playlist folder should contain all tracks contained in all smart playlists, but it doesn't. Only the content of the first smart playlist is shown. Is this a bug in iTunes or am I doing something wrong? Thanks.
