Wisin & Yandel are a Puerto Rican world/reggaeton/"urban pop" duo who have collaborated with everyone from 50 Cent to R. Kelly to Lenny Kravitz and Enrique Iglesias, and they've sold approximately a gazillion albums in Latin America, Europe and elsewhere. In case you were wondering if reggaeton is still a thing, I guess that's a pretty definitive answer.
