Query: smooth harmonies & up beat tempo songs are the best on here!

If you don't know who the Barrio Boyzz are...where have you been? These Boyzz are the greatest! The "Ven a mi" cd is great to listen to if you want to party. "Rico", "Se me fue mi vida" "Loquera" are the best songs! And if you like slow songs...theres "Ven a mi "(which is my favorite) "Sere tu rio" "Si eres tu" are good to relax to. I like the harmonies and smooth flava these guys have. It truely deserves 5 stars!
