I'm using Windows 7 to do this. I have quite an extensive library of music and now I have quite a lot of duplicate tracks but in different albums. Obviously I don't really want duplicate files but I'd still them to appear in all of the albums they should. The biggest example I have is that I have multiple UK Top 40s now and some songs are in the charts for weeks, so I have multiple versions of that song which I don't want - but I do want to be able to see the track in each week still. (On my iPhone...)
Is there any way to do this in iTunes? I don't mind a bit of tedious work if it means I can eliminate duplicate tracks!
