Try this?
.media_panel { background: transparent; padding: 0; margin: 0; position: fixed; bottom: 0; left: 0; width: 100%; }
.media_panel h2 { display: none; }
.media_panel embed, .media_panel object { height: 25px; width: 100%; }
Also, you'll need to use this URL format to make it look like the bar instead of the thing where the bar minimizes.
http://youtube.googleapis.com/v/VIDEO_ID?version=1&autoplay=1
Where VIDEO_ID is the id from the video, as shown in red in this URL:
http://www.youtube.com/watch?v=uDuRcGG0PWY
There's a good chance your video won't work once you change the URL though because it contains content from Sony, so you'll need to look for another song that isn't from one of the big publisher channels like Vevo.
