@Mike:
The possibility to rename the custom fields would be very welcome.
And I see the need for more custom fields and more custom groups.
@BobbyH:
Please note the general difference between the text fields Custom and Custom 2 and the Custom Group
It's not only that the text fields cannot be renamed. Their content has to be entered individually for every song that should use it. The Custom Group creates a selection list and is handled similar to MSPs native groups like Albums, Genres, Composers ...
