How fitting that Rihanna recorded much of her sixth CD in hotel rooms: It's all about sex! "I know you want to bite this!" the diva declares on the throbbing "Birthday Cake," and she begs a suitor to "be my sex slave" on the thrilling "Cockiness (Love It)." Still, with such exquisitely produced dance grooves (i.e. the beatific No. 1 single "We Found Love"), it all sounds anything but tawdry. (Island/Def Jam)
