If looking inside someone's iPod is like looking inside of someone's soul—like someone must have said somewhere at some point—then Barack Obama's soul is somewhat of a mixed bag. In an interview with Rolling Stone, Barry revealed the artists who dominate his iPod, from the kind of awesome (Bob Dylan, Howlin' Wolf, Jay-Z) to the awesomely lame (Yo-Yo Ma, Sheryl Crow, Springsteen). It's kind of disappointing, really, to learn that Mr. Transformative isn't at least bumping a little Public Enemy or Thin Lizzy, both of whom really did change everything. But, hey, at least he's not an Abba fan.
