Don Omar

For all the adolescent preoccupations (sexy robots! sexy-but-evil scientists!) and the played-out man-vs.-machine anxiety, iDon is probably reggaeton's first bona fide concept album. It also happens to be -- by far -- Don Omar's best. Omar wisely chose quality over quantity: The album tops out at 10 tracks, but each one features hot, distinct riddims, while his rapping has gained nuance and abandoned the abrasive shouting of yesteryear. "Ciao Bella" even reaches out to ballad-lovers without sacrificing Omar's cred. Three tracks appeared in the 2009 film Fast & Furious.
