I want there to be duplicate entries in different playlists

I can see that you'd want duplicate entries in playlists. One problem I can foresee is with my taste in music. I listen to a lot of 'Trance' and 'Techno' music and much of it is on compilation CDs. If I have a duplicate track (exactly the same name and artist) it would be great if 'something' other than me could determine this and just put a playlist link instead of another MP3.
