Despacito by Luis Fonsi have got over 3.65 Billions of views on Youtube. It's considered to be one of the most viewed videos on youtube if I'm not wrong.
Everyone talks about this Puerto Rican Sensation who became a talk of the world overnight. This song gave him world recognition. But, nobody talks about the importance of Daddy Yankee in that song.
Think about this song without Daddy Yankee. If you have the high-end software, if any, mute the Rap portions sung by Daddy Yankee and then listen to this song. I am 1000% confident that the output wouldn't be the same.
