It would be great if there was a button added under Playback to love the current track.

Looking over the API, it seems like it may be a little tricky.

Sure, it'd be easy enough to use the Track.love method but then that doesn't allow the user to unlove the track.

You could make the button unlove the current track if it's already loved but I can't see a way to check if a track is already loved by the user.

There is a User.getLovedTracks but that returns a set of tracks and not an individual track's loved status. Then you're getting into parsing and keeping track of all the user's loved tracks and that sounds doable but a nightmare tbqh.

I think just the Love button would be good for a start at least.

I wonder how the official client manages it.
