All of my edits (misspellings and corrections) were done within MB. I double checked to see if any files still have the "Downtemp" tag, and none of them do. Even after restarting MusicBee, the tag is still in the dropdown. Other tags that I haven't used specifically, such as "Hip Hop Music", "Pop Music", and "Alt Rock" still appear even though I've never used them. Still unsure how to get rid of these.
