"Weird Al" Yankovic - NOW That's What I Call Polka!

A fanmade video for Weird Al's 11th polka medley, NOW That's What I Call Polka! From his most recent album, Mandatory Fun.
Making this video made me aware of just how weird pop music has become. For example, this polka features:
1. A comeback by a Disney star/country star's daughter about riding naked on a big black ball
2. A song about murder
3. An obnoxious boy band that rips off both The Who and Tenacious D in the same song
4. A fat Korean pop star who dances like Monty Python pretending to ride horses
5. A plain obnoxious song that somehow nobody could stop singing
6. A comeback by both Britney Spears and will.i.am that features a hook reminiscent of the chant of the guards from The Wizard of Oz
7. A one-hit wonder who basically stood in front of a white wall and let himself be painted naked
8. A dance song by Pitbull (weird enough that he's still making hits), but with Ke$ha and with the main tune played on a harmonica
9. Two guys who wear speedos and thrust their crotches
10. A song with the line, "I wear your granddad's clothes, I look incredible"
11. And a comeback from a '70s funk guitarist, an unknown producer, and two robots that somehow resulted in the only dance song actually worth dancing to.
