[Party Rock Anthem] How did the song turn into a mind-affecting virus?

Also, how are people alive if all they've been doing is "party rocking" for a month straight? Not sleeping for that long has got to do a number to your system, doesn't it? Wouldn't everybody be dehydrated?  
  
EDIT: Some more questions. Is there a cure, or are you done for once you've heard the song for a certain length of time? Does it only affect humans? People who are affected only seem to attack those who aren't dancing, but how little can you do and still call it dancing? Would it affect wheelchair-bound people differently? How do "infected" people infect the deaf? Would it affect sentient AI if they had mobile limbs? Where is the music coming from in the first place?

it's simply another musical virus of the kingdom "rhythm" similar to the "Funk" that was first spread by Parliment. patient zero is rumored to be Bootsy Collins. Most people are Carriers of some "Rhythm" virus although curiously African Americans seem to have a higher carrier rate than almost any other ethnic group. the thing about the kingdom of Rhythm viruses is that we actually have a symbiotic relationship with them. they are important to our mating rituals. though not essential.

how one contracts "The Funk" is simple. once enough carriers band together in a band and then become popular enough. the disease hits critical mass and becomes airborne. generally Rhythm Viruses are mostly harmless. usually only resulting in extended dancing and joviality. for most the symptoms only last a weekend and they wake up fine on monday morning, though sore legs and hangover's are not uncommon. and Rhythm Viruses shape culture in more ways than almost any other microorganism. for example India has been in the grip of the "Bollywood" virus for years. and they function fine. after a while the virus mutates and changes "genres" as a effect of evolution. for example the Black Metal and Death metal Rhythm viruses(which show as excessive Headbanging as the primary symptom) come from the same "Metal" parent virus.
