the pre-chorus verses right before the chorus " don't want ur silly games blah blah blah" sound weird. it doesn't flow with the beat. The song reminds me of a mix of Kids In America, another song, and an Activia commercial jingle (activiaaaaaaaaaaaaaa).
Reminds me of an Old Navy commercial. The song is bad. She's too old for this. I don't get why she's doing this. Is she trying to say women in their 50s can still be sexy? Yes, they can, but not by acting like high schoolers.
The video looks kind of cute. It's nothing absolutely spectacular but I guess it does it's job to cater to a 'cheerleader' song. As for the song, based on the preview, I'm not feeling it at all. I hated the demo and this sounds exactly the same to me. It is incredibly catchy though.
Not much has changed from it either. 
looks very neat
