Working good on my Chrome, OS X.
And I think it's a great project, will check out the github.
A suggestion would be to change the play-icon to pause and add some kind of progress bar to it when a song is playing?
if you want you can show the youtube player in a corner you put this css in the secret's div on the footer :p "position:fixed;right:0;bottom:0;width:420px;height:315px;"
thanks for comment!
