Thanks for this awesome script!
I have some suggestions:
-I'm missing the possibility to turn off MusicIP search and just use Artist+Album, like normal Amazon search. Much of my music is already tagged well, and I mostly use this script to get the Release type, and it would be quicker if I could turn off the MusicIP when I don't need it.
-It's also a bit annoying that when an album have multiple discs it only searches for one and one disc, but maybe this is because of MusicBrainz' database.
I prefer to have the same album name for all the discs and rather tag with Disc#.
-A possibility to save the earliest release of an album in the Original Date would also be nice. I often have e.g. a 2001 remaster of an album, and it would be nice to have the original release date also stored.
