I don't get it, I only use Groove on my 1520 and 950XL. And I only use it for music I load onto my SD card. I do not use Groove Music Pass or download anything. Yet, I have Artist's and their CD's showing up in my Groove app that I did not add and have never owned or heard of. Yet there they are, under my Artist list. What the hell is that about. Not only that, Groove will take an artist folder and move some of those CD's to other areas. Drives me nuts.
