I've got a stupid question (SQ) that I'm asking mainly out of curiosity but also for future reference. There was a big VD (Valentine's Day) singles event this year that was to have a band for dancing, but there was no indication of what kind of dancing. So I Google'd on the band's name (long since deleted from my Palm) and all it said about then was the number to call to book them and that they play "dance music". No playlist, no indication of what style, no naming of what kinds of dances, no naming of what decade, no nothing except "dance music". So I assume that "dance music" is a stock term that everybody knows within the popular culture (of which I have not been a part for a few decades now). So what is "dance music" and what should I expect when a "dance music" band plays?
