Puerto Rican duo Wisin y Yandel is without question the most successful reggaeton act in the history of the genre, outselling all the other heavyweights. Anyone remotely familiar with the genre will recognize their song "Rakata," originally off the Mas Flow II (More Flow II) compilation and then later released on 2006's Pa'l Mundo (For the World). That, along with "Llame Pa' Verte" ("I Called to See You") off the latter album, solidified them as major players in what many people have recently dubbed a waning movement.
Funnily enough, since the release of their last two albums, 2007's Wisin vs Yandel: Los Extraterrestres (The Extraterrestrials) and this year's La Revolución (The Revolution), the two have insisted that their music isn't reggaeton at all, but rather pop. Either way, they've continued to dominate the charts with songs such as "Sexy Movimiento" ("Sexy Movement") and their collaboration with 50 Cent, "Mujeres in the Club." These tracks display a clear evolution from the standard dembow beat so easily recognized (and abused) by many reggaeton proponents, instead opting for electronic beats and melodies consistent with those in mainstream pop and hip-hop.
This evolution seems to suit the pair's fans just fine, though. Since its release this past May, La Revolución has dominated Latin sales charts, and Wisin y Yandel's popularity seems more firmly rooted than ever.
