Empty queue restarts current song
Mobile
On mobile, emptying the queue restarts the current song from the beginning. The queue is then empty, but a song is playing. You see the buttons to pause or restart the song, but no info on the current song.

On desktop, emptying the queue will stop the current song, but clicking on the play button will start the last played song from the beginning, but the queue will still stay empty. Clicking again on "empty queue" restarts the current song from the beginning, as on mobile
