Ok, no video, but this is what I did.
First, I went and found a You-Tube vid I wanted, and copied the ULR....
http:/ /www.youtube.com/watch?v=ANTYbInzdoA
Then from that, I took out the last part.... ANTYbInzdoA
.....And inserted it in 2 places in this code....
<object width="" height="0"><param name="movie" value="//www.youtube-nocookie.com/v/ANTYbInzdoA?version=3&hl=en_US;autoplay=1" /><param name="allowFullScreen" value="true" /><param name="allowscriptaccess" value="always" /><embed src="//www.youtube-nocookie.com/v/ANTYbInzdoA?version=3& hl=en_US;autoplay=1" type="application/x-shockwave-flash" width="0" height="0" /></object>
See where I put the.... ANTYbInzdoA ....part of that ? (for your song, you will have to substitute your music ULR....Use the part after the = ....Insert it in those 2 places between the /v/ and the ?
Next, I went to my Profile, then to 'Ultimate Profile'....In the big box at the bottom marked "Customization: ", I copied and inserted that entire code above, and saved it.
And I had music. Hocus Pocus.
