What's Mitt Listening To?

A photo caught Mitt Romney in a personal moment this week, ear buds in, listening to something.  What's he listening to?

"Transvaginally Probing Your Inner Vagina... Chapter 1..."

"Money, money, money, mooooooooney.... moooooney...."

"Goodbye, Hispanic vote... Adiós, voto hispano..."

"I gotta be meeeeeeee... I gotta be meeeeeee..."
