I love this song! I listen to it every day. But..... there IS some inappropriate material.
There is no violence, no gore, nothing like that. I think parents should pay attention to the lyrics and the video ( mostly the video ). Lyrics can be a little touchy: " Put your hands up, make them touch " is a part of the chorus. Very.... strong outfits are used. One is a shirt ( well, more like a bra ) that has hands on the front. In one part, she is only wearing cover ups, NOT clothes. She can have strange.... strange moves in the music video. That's all there is to worry about :D
