OK, that's good to know.
What's the best way for me to fix my results for such songs, or songs that aren't in the ENMFP database? I was planning on doing a track/upload for each of these. Is that the right thing to do? That is, is it a problem if I were to track/upload that David Bowie song of mine? It seems that it will duplicate an existing ENMFP in the database but with different info (Artist, SongTitle, etc.).
