Okay, listened to a few of her most popular songs to see how I felt:
Bad Romace - Awesome chorus, pretty bad everything else
Alejandro - It's okay, meh at parts
Dance In The Dark - Like it
Telephone - I would rather die than ever hear this song again
Disco Stick - I would rather die than ever hear this song again (2)
Poker Face - I actually like this
Paparazzi - I really like this too, and not just the piano version
I don't know, I think I like a third, indifferent/okay with another third, and absolutely despise the last third
