Reggaeton's duo dinámico, Wisin y Yandel, was the big winner at last night's Premios Juventud in Miami, scooping up four awards for "My Favorite Video," "CD to Die For," "Favorite Urban Artist" and a new category, "Favorite Ringtone" (when will English-language shows get smart enough to pick up this category?) It was a also a big night for Jennifer Lopez, Ricky Martin and Aventura, who followed WY closely with three awards each.
