3.0 is a really good album of salsa music by Marc Anthony. The songs have a lot of energy and the entire album keeps moving along fast. Some of my favorite sare "Vivir Mi Vida", "Volver a Comenzar", "Espera", "Hipocresía", and "Vivir Mi Vida" (Versión Pop). 3.0 is an album for all salsa fans. I also like his Marc Anthony, Mended, and El Cantante albums.
