It was also one of President Bush’s favorite tunes (via ABC News):

Also on the “First iPod” is the rather naughty 1979 song “My Sharona” by the Knack, about a man pursuing a much younger woman. Among the song’s lyrics: “Keeping it in a mystery, it gets to me, running down the length of my thighs, Sharona.”
Said [David] Itzkoff: “This wouldn’t be consistent with Bush’s image as protector of conservative values.”
“No one should psychoanalyze the playlist,” said [Mark] McKinnon. “It’s really just great songs designed to for a great workout. And if there any songs in there with controversial lyrics, I’ll take the heat for that.”
