I talked briefly about this issue before in an comment with another user who is no longer on this site/I haven't seen this Carat for a very long time here, and wondered if I could make a post talking about this quickly since I can't help but feel like I'm going in circles about this.
I loved a lot of these artists in the screenshots of my Spotify account, however with inactive companies + little to no social media updates, and failure to update their Spotify pages with their current things, and some talk around fans about not only disbandment but dis interest in the KPOP scene at the moment, and that KP isn't that deep, I know I enjoyed the artist and followed them before () said member left or joined a different group and that it's okay to step away from them. And that I don't need an answer if I don't want to follow them anymore.
I have since unfollowed 50 artists, a lot of which have been un active for a while/ no longer interested in.
Do you still follow unactive groups/ how did you choose to clean up your Spotify?
but if an artist/group was inactive then yeah I'd unfollow them.
