If you've never heard the Kidz Bop series (from the makers of the series Now That's What I Call Music!), consider yourself lucky. If you have, you know how disturbing it can be. They claim the songs are "kid-friendly versions of today's biggest hit songs" but I don't know how children singing them make them kid-friendly. They range from the bizarre (Modest Mouse's "Float On") to the entirely inappropriate (Britney Spears' "Toxic").

The latest edition, Kidz Bop 8, has U2's Vertigo. Listen to the audio clip if you dare.
