My workaround uses the ratings. For example, "When Doves Cry" is on both the "Purple Rain" soundtrack and "The Hits" compilation. I gave the track 5 stars for the former and 2 stars for the latter. My preferred playlist is Smart and Live Updating. It does not consider any track with 2 or fewer stars. Anytime that song is played it's the original version and that track's Play Count (which I care about for some reason) is the one that matters. However, since the track from "The Hits" remains checked the duplicate track will play if I choose to listen to Prince's greatest hits.
