So, while playing tracks, display "All Tracks" in the main window (centre), using List view, or list by album view with artwork if you like. Then sort the entire list on the rating column.

If you only want to see songs which appear in current playlist, display that, instead of all tracks.

Then while focus is in the middle window, start typing the name of the artist, and the search results will appear in rating order.

Same happens again if you type some other name.

You can sort on many columns, including Rating, Title, Album, etc. If this doesn't work, you may need to switch View. For example List View is very flexible in what columns to show, and what to sort on.

I hope this makes sense but Say I am listening to a song I really like, so can I search by that Artist and than be able to see the rating's in order for just that Artist? Music>Artist then instead of having the song alphabetically they list by rating for that Artist.
