As I stated above:
Last.FM will continue to be queries as long as unmatched media remains in your library. A tool , such as Picard, can help resolve that.
Get a music naming & tagging tool.
Correct the naming, tags, and structure of your library (curate it)
Either “Plex Dance” the specific media (which normally happens when you use Picard and move results to a new location), recreate the music library, or force refresh.
