I was looking for a Google Play Music tag source a couple of days ago and only could find one that worked partially so I have been improving it and it's now working for me.
You can try it and make suggestions or tell me how to improve it. Enjoy!
Google Play Music v1.02.src (22.3 KB)
[2018-11-22] v1.02 FIX: albums with no genre information were not parsed correctly. FIX: multi-disc albums were not parsed correctly. Now working for up to 20-disc albums.
Google Play Music v1.01.src (13.6 KB)
[2018-11-22] v1.01 FIX: multi-disc albums were not parsed correctly.
Google Play Music.src (6.7 KB)
[2018-11-19] v1.00 based on Tag Source for Google Play Music by SheepKid12
Please note, the tag source works only in countries where Google Play Music is available at the moment.
