Co-written by Luis Fonsi, Erika Ender and Daddy Yankee, the massive viral hit "Despacito" earned Song Of The Year honors at the 18th Latin GRAMMYs.

"Yeah! What a night. What a night. Thank you very much. Thank you to the Academy. What a blessing. What a privilege to make songs [and] that our job is to make songs [and] communicate through music. Thank you very much Universal Music, Sony/ATV, Sebastian Krys [and] to all involved in this song. To this woman who I have on my left, Erika Ender, the co-author of "Despacito." To Daddy Yankee, the co-author of "Despacito." Thank you. Thank you. I share this award with all of the nominees. With all of the people that live the music. Long live the music in Spanish!" — Luis Fonsi

The song won four Latin GRAMMY Awards, a total rounded out by Record Of The Year and Best Music Video (Short Form) as well as Best Urban Fusion/Performance, for the remixed version featuring Justin Bieber.

Amid a summer spent reigning over the U.S. pop charts, "Despacito" became one of the most-watched YouTube videos of all time. Tonight's wins bring the Puerto Rican Fonsi's career Latin GRAMMY count to five, having previously won Song Of The Year for "Aqui Estoy Yo" at the 10th Latin GRAMMYs.
