Crystal now number 6 on Billboard dance chart

Chart dated 9/29; up from number 8 the previous week.

Has anybody in the U.S. actually heard Crystal played in a club? If so, which version?

I haven't gone to any clubs as of late. But I don't think they would play it in the Grand Rapids, MI area. It's all booty / hip hop dance music in the clubs around here. The only club they would play at would probably be Club 1894...as it is more techno oriented.

What does No.6 on the Billboard Dance Chart actually mean?

Sales, airplay, someone who compiles the charts likes this song?

The complete title of the chart is Hot Dance Music/Club Play. As far as I can tell, they don't explain how they arrive at the rankings. Look for yourself: billboard.com.

I was wrong. At the bottom of the chart it says "compiled from a national sample of dance club playlists."
