I am a newbie, so please bear with me.
My music collection is in flac format and tagged with mp3tag.
I wish to add songwriter tags (multiple for some tracks).
This is to have the tags read by JRiver Media Center so that I can play tracks written by a specific songwriter eg. Irving Berlin.
I have a database (Music Collectorz) where I have painstakingly input songwriter data. Such data can be exported.
The question then is: What import format/syntax is recognized by mp3tag so that I can import the songwriter data into the songwriter tags?
Many thanks in advance.
