The issue here was that if we couldn't find a track from a musicbrainz
ID (which was almost never), we would fall back to just creating a new
track with a blank album. So we'd spam the track table with identical
tracks just no albums.
Now we do a quick check for the track where the title and artist match
and use that if it's found. This will result in some tracks being
associated with the wrong album, but I think that's better than the
current behavior.
