Is this bad?

So there is this group called Metro Station and they sing a song called "Shake It". It sounds very 80's and I find myself bouncing along to the tune. However, I'm not the only one enjoying the song....Gianna LOVES this song. She stops whatever she is doing when the chorus starts and dances! It's adorable. The problem - I don' t think it's a very appropriate song for an 11 month old.
Come to think of it, when Gemma was her age her favorite song was "Like a Virgin" by Madonna and Spencer loves the Red Hot Chilli Peppers. Maybe I need to make different music choices.....By the way - once you hear this song, it keeps going over and over in your head....
