Malditah Musings

My fiance and I are getting married in a few months and I am currently working on putting together the song list for our reception. We already have a great DJ reserved to play all of the traditional 'wedding-y' stuff early on and then later in the evening music that we enjoy (mostly hip-hop, r&b, and rock)

Sooooo, my question is what are some really good cha-cha and/or salsa songs that anyone would love to dance to? I am filipino (we love us some cha-cha) and his family is hispanic (salsa is in their blood) so I am trying to have a few songs of each to really get the dance floor pumped.

p.s. yes, i know that i can do a related search on youtube or itunes, but i would like some suggestions from real experts on what are just the main songs of that culture. i.e. a lot of american weddings play the Cha-Cha Slide as a song everyone knows and dances to, etc.

Thanks in advance for any of your help
