Mute until next track starts

turntable-track-muter.js

(function(){
	function toggleMute() {
		$(".mute_btn:first").click();
	}
	toggleMute();
	console.log("muted!");
	var $messagesDiv = $(".messages");
	
	function onMessageReceived(event) {
		if (event.target.tagName !== "DIV") {
			return;
		}
		var $message = $("div:last span:eq(1)", this);
		setTimeout(function() {
			var message = $message.text();
			if (message.indexOf(" started playing") !== 0) {
				return;
			}
			console.log("volume up!");
			$messagesDiv.unbind("DOMNodeInserted", onMessageReceived);
			toggleMute();
		}, 25);
	}
	
	$messagesDiv.unbind("DOMNodeInserted", onMessageReceived).bind("DOMNodeInserted", onMessageReceived);
})();

$(".mute_btn:first").click(); doesn't work anymore.

Try $(".volume-icon").click();.
