I would like to delete/unlike all my liked songs at once. The answers I've found describing how to do it say to go to the "songs" folder in the left panel, but I don't have anything that just says "Songs" in the left panel. I see something called "Liked Songs" though. When I click that and follow the instructions I found, which say to hit Cmd+A and then right click and choose delete or hit the delete key, nothing happens. It doesn't work.
