As a predominantly metal, rock and punk fan, people act suprised when I like the Russian pop duo tATu. I also like a few Britney and Katy Perry songs like Everytime and Cry About It Later. Oh and because they amuse me, E-Rotic with their cheesy innuendo filled euro dance.

Lil Mariko does the whole schizophrenic kawaii bimbo to aggreesive thing really well.

Little Big should also be more popular then they currently are.

Oh and Hello Kitty by Avril Lavine is a bop and isn't that much of a shock if you compare it to Girlfriend, but is obviously the seemingly opposite of Complicated.
