Rarely seen on the campaign trail without his trusty iPad, Mitt Romney unveiled for the first time today a glimpse into how he uses the popular device, releasing a hand-picked playlist of his go-to music on the road.

The list of 19 songs - a collection of movie soundtrack songs, American Idol pop star tunes and a whole lot of oldies - were chosen by the candidate, according to the campaign, and will be made available on his Facebook page through Spotify, a free online music sharing program.

Unlike the Obama campaign's release of a campaign playlist on Spotify last month, this list is strictly a glimpse into what Romney pumps through his ear buds every day.

An advance peak at the list by ABC News shows plenty of oldies - much of the music the campaign plays prior to one of his campaign events - including Johnny Cash's "Ring of Fire," "December 1963? by Frankie Valli & the Four Seasons, and "Good Vibrations" by the Beach Boys.  There are a couple of Roy Orbison songs and Willie Nelson's famous "Over the Rainbow" also gets a spot.

But the rest of the one-hour playlist also provides interesting insight into Romney's taste in music. There's plenty of country on the list - songs by Tim McGraw, Clint Black and Toby Keith. A self-confessed "American Idol" fan, Romney also has Carrie Underwood's "All-American Girl" on the list.

A song from Romney's favorite movie, "O Brother, Where Art Thou?" tops the list, The Soggy Bottom Boys "I Am a Man of Constant Sorrow" in the No. 1 slot.

More recently recorded tunes on the list include two songs by The Killers, "Somebody Told Me" and "Read my Mind."

And what would a Mitt Romney playlist be without some Kid Rock?

That's right, the rock star's "Born Free," the campaign's official song, earns a spot on the candidate playlist, suggesting that he is still not tired of hearing the song that is pumped through speakers at his events on repeat several times a day.
