"Shake It" is a catchy song, with some sexual undertones. Besides the "You're on the bed but your clothes are lying right there" line (to which my friend responded "They're in their PJs!"), not much of the content is obviously pertaining to a physical relationship. Most younger kids can't read into lines like, "I'll take you home, If you don't leave me at the front door" enough to understand the song's real meaning. Overall, it's a great song.
