Chicas,
I found a beautiful song called "Me Enamore De Ti" (I Fell In Love With You) by Chayanne. It's from a telenovela called "Corazon Salvaje." The song makes me smile everytime I hear it. It's truly a beautiful song and would be great to use as a first dance or cake cutting song. I Just wanted to share it with you in case you are still looking for a song to use.
