Amazon.comThis collection has a split personality. On one side, there's the youth Moment, led by 12-year-old Aaron Carter, the younger brother of Backstreet Boy Nick, No Authority, and Jessica Simpson. On the other side, there are the established artists, who are true surprises. Sinead O'Connor? Cyndi Lauper? Isaac Hayes? So, it's a battle between bouncy pop with its hyperextended beats and clear skin and the ragged tone of world-worn former heroes. Things begin with a surprisingly mellow track from TLC's Tionne T-Boz Watkins (perhaps she can't figure which side of the fence to choose here). From there, the beats step up, and Aaron Carter, Baha Men, and Jessica Simpson all deliver the kinds of catchy tunes you expect. Sinead O'Connor hasn't abandoned her sententious beginnings. Even with the addition of hip-hop beats and a few random electronic noises, she still sounds as solemn as ever, whispering and singing softly. Former Spice Girl Gerri Halliwell updates Nancy Sinatra's "These Boots" without adding or subtracting much. A better novelty is Cyndi Lauper performing "I Want a Mom That Will Last Forever," a sentimental tune perfectly suited for her emotive reach. --Rob O'Connor
