I love MP3Tag, i've been using it for years, but have hit the wall while making some big changes to my music collection.

I want to replace the ARTIST field with info after the '-' gleaned from the ALBUM field.

All the ALBUMS are titled as follows:

Fabric 02 - Terry Francis  
Fabric 03 - Jon Marsh

What would be the best way to do this?

thanks in advance

You can use a 'Guess Values' action, defined as follows:

_Action type:_ **Guess values**  
_Source format:_ **%album%**  
_Guessing pattern:_ **%dummy% - %artist%**
