Yes this is 8 minutes long but this is brilliant! It's done by a guy named Daniel Kim and it's called "Pop Danthology 2012".
He put out similar videos in 2010 and 2011. This one includes clips from Carly Rae Jepsen's "Call Me Maybe", Demi Levato's "Give Your Heart A Break", Psy's "Gangnam Style", "Some Nights by Fun., and 46 more!
(By the way my grammer is not wrong. If you don't know already, the band Fun. uses a period after their name) :D
Check it out now!
