Is anyone else having trouble getting duplicate songs to add? For example if I add an album by an artist, and also their greatest hits, all the songs that are on the original album refuse to add to my collection on the greatest hits. I get that its a good way to avoid duplicates, but sometimes they are slightly different versions, or you just want the duplicates so you can play each album through in full. I can't find a way to over ride this which is a bit irritating. I may have to go down the Playlist route for all greatest hits albums.
