Ok so I have a fairly large music collection (around 50k songs) and when I used to DJ I would have many songs to have multiple genres listed eg: Taylor Swift - Love Story had the genres
Today I no longer DJ so multi genres is not needed. Now I have a stream radio station that ONLY reads a single genre from the genre tag...anything more is not read. So my question is what should I need to do in order to simply bulk edit the tags to remove all but the first tag? All the multi tag songs' tags are colon separated.
You could try an action of the type "Split field by separator" with the semicolon as separator
and then an action of the type "Remove duplicate fields"
or you could try Convert>Tag-Tag for GENRE
Format string: $regexp(%genre%,(.*?);.*,$1)
BUT: why throw away that painstakingly gathered data in GENRE only because your current player ignores most of it.
If you should switch to another player that might be able to cope with more genre data, it would be hard to restore.
