In case anyone's wondering what Old Flames might be, it's a country song written by Ke$ha's mother that was eventually covered by Dolly Parton. I can't wait to hear K$'s version. In spite of the fact that I don't really like the genre, I've loved all of her foray's into country music so far, and I think it's really kind of special that she'll be singing something her mother wrote long before she was even born.
Also, I think this pretty much confirms that Supernatural will be a single at some point.
