In this thread people are labouring under the false impression that Disco is dead. Disco never died. Instead God took Disco, like he took Enoch in the Bible, and it avoided the death that most other music forms have suffered over the ages 
Hell, I think the old disco is making a bit of a comeback these days; it seems to be rather more popular among those who missed it the first time than it was just a few years ago, or at least, that's my completely anecdotal opinion.
