Latin band with Andy and Francesca

The Latin song played by that Latin band that was being played during the scene where Andy and Francesca were at the restaurant, then dancing, then having sex was the song La Gallina Fina by Sammy and Sandra Sandoval. Even though this is probably the best music in the movie, I don't think this song was on the Soundtrack for this movie. Heres the link:
