My layout is as follows:
screenshotAs seen in the screenshot, I have set to display 'Album Rating' below each album cover in the main panel.
and to show 'Track rating' and 'Love' in the 'Playing Tracks' in the right sidebar.
Also,
Regarding '"Album Rating":
The 2nd album, "Burning Organ", has 5-star rating.
All the rest albums that have no rating, but unfortunately have their 5-star element visible(dimmed).
Regarding '"Track Rating" and "Love":
In the "Playing Tracks", only the track "Burning Organ (instrumental)" has rating (5-star), and 'Love'. All other tracks have no rating nor 'Love'.
The 'Track rating' is indeed invisible for all other tracks, until you click to focus their row
(in the screenshot I have focused the track above it, "I Feel Love" ).
But unfortunately the 'Love' icon is visible(dimmed) for all these tracks.
So my suggestion is:
the "Album Rating" elements in main panel, as well as the "Love icon" in the right panel,
both to be initially invisible if there's no rating/Love, until you you click to focus them.
Here is a mockup to see what I mean:
