I'm firmly convinced that any song can be danced to either, foxtrot, rumba, or mambo. I think Roxy Music's Avalon album is perfect for rumbas, but that has never occured to most people, I get them to do it with me any way. I like to do most East Coast Swings as fast foxtrots, just becuase I think they're more fun that way. In the words of that wise old sage "If it feels good do it!"
