Renaming Files with a m3u as source

Hi there.
I might have shot myself in the foot with not making a backup first and being to lazy to review changes.
Well, long story short:
I have several albums/folders which Picard looked up, assigned the wrong album and I now have for whatever reason the songs an ace of base album (some special editition) partially renamed to smashing pumpkins songs.
Any advice how to get out of that mess/fix it? The album in question is not listed on musicbrainz.
what I still do have - that’s why I chose the topic is the original m3u with a the correct names.
Sure I could edit everything manually, but since it affects several folders that would take ages.
any helping hand would be greatly appreciated.

What I think you are saying is that files were mapped to various releases and then when you saved, their tags were updated to something incorrect and the files were renamed and moved to various other places on your disk.

So to fix this we need to correct the tags, rename them correctly and move them back into a release directory.

To achieve this you need to do two things:

  1. Create a release on Musicbrainz for this album.
  2. Bring that release up in Picard and then drag the files from Explorer into Picard and assign them to the correct tracks (maybe by listening to them), and then save.

If you cannot find details of the album elsewhere (e.g. Discogs) then you can use the m3u file as the basis for creating the release in MB and hope that someone with more knowledge fills in any blanks later.

Picard itself does not have an option to get the data from a m3u playlist.

But do the folder and file names provide artist, album or title information and are they still unchanged (i.e. you only saved new tags, but did not use Picard to rename files)?

If yes you could use the “tags from filenames” functionality to fill in the basic tags, see Generating tags from file names — MusicBrainz Picard v2.12 documentation
