Say I have a track that has a different track title, artist, and year from current tagging.
Right now I only want year, because Idon't like the title it generates, but do like the year. I go into setting, select only 'Find track year' and 'archive values.'
Music IP Tagger does its thing, looks up the track, finds just the year, and I tell it to Auto-tag. Success, and there's even a nice-looking code in the comments (where I told it to store the PUID)!
HOWEVER, when I then go back to run the script for just track title, or just track artist, or other things, 'Using existing PUID values,' it reports success in looking it up (and goes much faster, clearly not re-creating the PUID), BUT doesn't actually find the changes it before suggested for track title, artist, etc. when I ran it for all of the values.
Concrete example: I have a track called Boys II Men - Motownphilly (1990). I run Music IP Tagger on it to look up track title, track artist, and year. It wants to correct it to Boyz II Men - MOTOWNPHILLY (1991). The artist and year look good, but I don't like the all-caps track title. So, I cancel out and run it again just for year (for now). I save the results, and it stores a hash-looking string in the comments. Now, I run it again with 'Use Existing PUID values' and 'Find Track Artist' selected, and it says success, but doesn't recognize now that Boys should be Boyz.
