Really like Groove Music but for some reason, one particular artist starting with the letter J shows up under Artists beginning with letter C. Have checked the tags and made sure there are no discrepancies. Removed the entire folder for this artist, restarted Groove Music. Album and Artist deleted properly, Stopped Groove Music. Re-added the folder, all with absolutely correct tags, though one song collaborated with an artist named Common but was deleted from the artist tag and replaced only with John Legend.
Restarted Groove Music and it added the songs and album, again misfiled under letter C. HUH???
