Looks good, but ran into loading spinners fairly quickly, large playlists kill this, I suspect because the api is not properly respecting the cache headers and is refetching the same information repeatedly and thus getting rate limited. Also

Once that happened I wasn't then sure if issues I'm seeing are from api or the app itself. It's possible this is prioritising the responsiveness of the UI rather than the actual speed of user interactions.

Also the menu bar icon doesn't work for me (on MacOs). I can see it, but it doesn't do anything and there's nothing in the app itself to enable/disable it (though thankfully it does respect cmd+drag to delete).

Also doesn't seem to remember player position between app openings
