Just read this on boingboing and found it too funny:

The president also has an eclectic mix of songs downloaded into his iPod from Mark McKinnon, a biking buddy and his chief media strategist in the 2004 campaign. Among them are “Circle Back” by John Hiatt, “(You’re So Square) Baby, I Don’t Care” by Joni Mitchell and “My Sharona,” the 1970s song by The Knack that Joe Levy, a deputy managing editor in charge of music coverage at Rolling Stone, cheerfully branded “suggestive if not outright filthy” in an interview last week.

So his friend Mark McKinnon gave him songs from his collection, thats stealing. [Link]
