Why Has Dancing Changed So Much?

As we approach an ELECTRIFYING, FUN-FILLED evening @ the 93.7 WBLK "OLD SOUL DANCE PARTY" this Friday @ the Hyatt Regency Hotel, I wanna ask YOU a question... WHY HAS DANCING CHANGED SO MUCH OVER THE YEARS? Dancing isn't even dancing anymore, in my opinion,....it actually SEX ON THE DANCE FLOOR!  What Happened?

Here's some video's from "Back in the Day"...and "Today"!  After watching, tell me what changed everything and why dancing so different now.
