Hi Ian,
I was facing a similar problem with my collection of 1,400 albums/ 20,000 tracks, where the tagging over the years ranged from good to appalling. My solution was to download a tagging product called 'mp3Tag' from the web. This is available free, with a voluntary donation option.
mp3Tag is superb, once you get to understand how its functionality works. It took me a couple of days to get into the swing of it, and to figure out how to make its 'functions' work, but once I got there, mp3Tag was absolutely fantastic!
How it works:
Load up an album into mp3Tag.
- mp3Tag shows the existing tag data which you can edit/ update at will.
OR
- mp3Tag gives you other options such as
Tag lookup and download the album tag data from the internet from MusicBrainz / FreeDb.
- Then mp3Tag gives you further options such as:
Convert existing track name from the existing tag data to your desired track name format.
The track name conversion is generated from mp3Tag functions which you can change or create to suit your requirements.
mp3Tag enables you to move/copy data from one tag field to another automatically.
So as an example, for normal single performer albums, I wanted to create my track names in the format of:
In the Artist folder 'The Eagles'; Album folder 'Hotel California' ;track name '01 - Hotel California'; and so on so I modified an existing mp3Tag function to give me this format.
For compilation albums with multiple artists, I wanted to have the track name in the format of:
In the Artist folder 'Various Compiation Albums'; Album folder '60 Number Ones of the Sixties - Disc 1'; Track name '03 - Roy Orbison - Pretty Woman'; and so on, so I modified the track naming function to do this.
mp3Tag enables you to do bulk updates of fields in an album, so this makes the re-tagging much quicker than I expected. When I began looking at re-tagging my collection, I thought that it would take me between 6 months and 1 year, doing say 5 albums per evening. With mp3Tag, I have just completed the job in about 3 weeks!
So that was my solution to the nightmare of re-tagging. I should say that I have no affiliation with mp3Tag other than sending a donation after the first day of using it, as I was so impressed with it. The developer sent me a thank-you for the donation.
Regards and good luck!
Peter.
