Getting rid of a 'rogue' song?

When I create new playlists from my Itunes library I often have what I will refer to as a rogue song hide behind another song's title. The song is one I uploaded from an LP. Incidentally, it's the Byrds doing Turn, Turn, Turn and it pops up behind other song titles. Any suggestions on how to be rid of it? I delete the infected song and it just pops up somewhere else. Thanks for any suggestions.
