I have a pretty big music library that I've collected over several years, using different methods of organization and library managers. Overtime, my library grew a bit inconsistent. Not terribly so, but mostly I've changed my mind on how I would like certain fields to be tagged, and some genres, artists, etc. have inconsistent spelling.
The worst part, however, is that I have an even bigger collection of songs waiting to be organized and put into my Library, since I neglected them for the past few years. A lot of them are from albums that already have some tracks in my library (I usually don't have complete albums, save for a few of my favorite artists, since I prefer to have only the tracks I actually like and listen to).
This poses a problem for me. I've been trying to add them to MB Inbox and auto-tag them in conjunction with the tracks already in my library, but this as been quite a chore, since there are so many files. I also would like to make sure that all the tracks from the same album have consistent spelling in its tags, as well as having the same release ID from MusicBrainz.
I would want to use a more 'automatic' tagger to make it easier for me (something like Picard, Beets, Bliss, Jaikoz, not yet decided), and tag both the 'unorganized' tracks as well as the tracks already in my MusicBee library. However, I don't want to lose my ratings and playcount if any files change location (if the spelling changes in any of the relevant fields, for example), and I also don't want to remap or replace files by hand in MB.
What's the best way to go about this?
