Mute Current Song Only

[Frick]

This has been suggested a couple of times, but the only way I can think of this making sense would be to add another button to the popup which I'm reluctant to do. I think a good compromise would be to offer a new button on the song notification that allows you to mute the currently playing song and unmutes when the next track starts. Thoughts? This seems more a matter of opinion and I would think matters to few.
