I have put together a blog for people looking for popular songs that are done in beats that can be danced to. I have a lot of latin dances on it, Cha-Cha, Rumba, Paso Doble, Salsa, Samba, and Argentine Tango. Ill also soon be adding a few others. In any case I'm just trying to spread the word, I spent a lot of time trying to find something like this when I started dancing and there just isnt much on the internet with this kind of information. If anyone is interested its at:
