The only thing I can think of is to use the "All Tracks" view in emplode and sort by song title. Scroll through and see if the same song gets repeated twice.

FAQ entries on this topic are here, but they don't cover your specific situation of having the same song from two different source albums. (Well, technically, it's not the same song, just very very very similar.)

Can anyone think of a way to use the Search feature to find only pairs of songs with the same title?

Do you really have that many duplicate songs just from compilation albums?

And something else to think about: Based on your description, this problem of having duplicate songs must also exist on your PC's hard disk, right? You're asking the empeg to solve a problem that already exists in your original collection.
