Last.fm/Libre.fm love button

### Problem

Thank you for this awesome software. I love its simplicity. But I use last.fm as a personal music tracker, to remember tracks I love. That's almost the single function I want from a music player.

### Proposal

A love button. But not like Clementine/Strawberry that has a bad implementation. It lets you love tracks on click, but does not show the loved state of the existing tracks. It would be awesome with a heart that's empty if the track is not loved, and filled if the track is loved.

### Prior Art (Optional)

A separate column would be nice (because then one could see tracks he loved in playlist easily).

if track is not loved 🤍 when it's loved:t: ❤️.
