My Tumblr: cosmosbeauty18.tumblr.com

There's a gadget from Mp3-Codes.com that is seems stuck in my page. I'm kind of mad that tumblr wont give us all of the html, now; the html code of the gadget does not appear in the theme html. So, I want to know if there's a way I could get rid of it... I got sick of the song

Thanks!
