All these views are just people hearing about this new video. I'd say the explosion in views and such will die down relatively soon.
It always happens. When someone has a viral video they try making another one but they try forcing it and it turns out to be shit. This will never catch on as much as Gangyam Style.
A millions views equals about $2000 in earning.
So by that logic, in a single day he's made more than what most average Americans make in a year (before the profit division).
