I can't understand how everyone has managed to overlook Brittany Spears! Also, have you never heard of Cher? And speaking of extremely talented, single-name singers, who could forget Melanie? ("I Got a Pair of Brand New Rollerskates," "Beautiful People.")Edie Brickell? Shanna Twain? Joan Jett? Pat Benetar? Also, I'm not sure if she's female or not, but I think Barney's sidekick, Baby Bop, is awesome!
