Cover art for Steam Engine lyrics by My Morning Jacket

I have the last line of this phenomenal song tattoed on my back' "The fact that my heart's beating is all the pr you need" and below it, the album's title It Still Moves in identical font from album cover. I love it. That line gives me goosebumps each and every (countless) time I hear it.
