Query: Very disappointed

I bought this CD because I liked one of their songs "Tiene Espinas El Rosal" and I thought they would have other nice songs. I was quite wrong. I found just about all of their other songs pretty boring. In fact, they tend to sound like they are all slight variations of one melody. They still sound all alike. The songs have a nice beat if you like dancing cumbia, but overall, there was not much listening pleasure.One more thing. Whoever came up with the idea of having some guy say random non-sense thing and yelling "pi pi pi pi pi" on just about all their songs, should be shot! It is very annoying and ruins the one or two songs that are decent on this cd.
