Right, that's another good work-around, to re-name the songs with a suffix indicator.

For me, though, I only do the suffix trick for different versions of the same song by the same artist. For instance, I have two different versions of Pink Floyd's "Mother" on my player (a live recording and a studio recording). I can see the difference between those two in a search.

But I have not re-named all of the versions of "Mother" on my player, which happens to include completely different songs by Tori Amos and Cyndi Lauper. So in that case, I'm still forced to find those tunes via the playlists rather than via a search.

I agree that sub-selecting search results would be a good thing.
