A Quien Quiera Escuchar is less "loca" then Ricky Martin's best-known bon-bon shaking material. There are some very pretty pop ballads on this careful, stripped-down production that plays up Martin's voice; notably "Naufragio," the whispery "Cuanto Me Acuerdo de Ti," and "Isla Bella," an ode to Puerto Rico. But of course the party isn't over. "La Morditita" is choreography-ready, and more fun than the single "Adios."
