The Genres, Top Artists & Your Top Albums is completely inaccurate. Most of the artists and albums aren’t even in my library. How can I flush the stale/incorrect data? How can I correct this situation?
Did you maybe play to some other zone in the background with no sound, and does this zone have Roon Radio enabled?
This would lead to all kinds tracks playing that you don’t know.
You can go to sidebar > History and delete them. Note that on a PC you can use the Shift key to select a whole range of tracks. However, the history is obviously chronological and has no filter option, so this can be tedious.
If cleaning out the history is not an option, you can restore a Roon database backup that is older than the issue. (However, you would also lose all other database charges that happened in the meantime)
When we have seen similar reports in the past, we’ve seen Roon Radio causing this, as @Suedkiez noted. Please try the history delete method and let us know if it helps, thanks!
