The Reggaetón Producer Insists You Sing the Hook on His New Track – intro video

You sing boleros at a small bar in Old San Juan, and for three nights in a row a grinning man sits in the back booth and slips you a note: “Come to my studio. Sing one line.” On the fourth night you finally go, meaning to refuse him to his face. He presses play: “This song has been stuck for six months. It's missing a chorus. What's missing is your voice.”
