// # SoundCloud Custom Player

// Make sure to require [SoundManager2](http://www.schillmania.com/projects/soundmanager2/) before this file on your page.
// And set the defaults for it first:

soundManager.url = '';
soundManager.flashVersion = 9;
soundManager.debugMode = true;
soundManager.useFlashBlock = false;
soundManager.useHighPerformance = true;
soundManager.wmode = 'transparent';
soundManager.useFastPolling = true;
soundManager.autoStart=true;


// Wait for jQuery to load properly

$(function(){
	
	// Wait for SoundManager2 to load properly
	
	soundManager.onready(function() {
		soundManager.defaultOptions = {
		  autoLoad: true,       // enable automatic loading (otherwise .load() will call with .play())
		  autoPlay: false,       // enable playing of file ASAP (much faster if "stream" is true)
		  multiShot: true,       // let sounds "restart" or "chorus" when played multiple times..
		  stream: true,         // allows playing before entire file has loaded (recommended)
		  volume: 80,          // self-explanatory. 0-100, the latter being the max.
		}
		// ## SoundCloud
		// Pass a consumer key, which can be created [here](http://soundcloud.com/you/apps), and your playlist url.
