#3  Song of 2010: Lady Gaga - Bad Romance

The Fame Monster, Lady Gaga's second studio album produced more global chart-topping singles like "Bad Romance" and "Telephone", along with unique and innovative lengthy music videos/short films. When you first watch them, you can't help but rub your eyes and say "huh?!", but after the tenth time, it's pretty hard to watch any other videos without falling asleep.

Gaga has ultimately changed the music industry, and her third album is one of the most anticipated releases in 2011.

#4 Taio Cruz- Dynamite

#5 Katy Perry – California Girls
