Nicky Jam has been in the thick of reggaetón since the late '90s, when he was a teenager speed-rapping R-rated duets like the pummeling electro burst "En la Cama" with his mentor, Daddy Yankee. In the '10s, Jam revitalized his career by veering away from his hard, fast, raw beginnings, refining a melodic sound perfect for slow dancing. "El Perdón" opens with plaintive keyboard chords that sway over a smooth dembow beat while the singer croons alongside a new partner, the ever-suave Enrique Iglesias. "Travesuras," meanwhile, rocks with seductive synths and a beat that's always changing.
