I think the song cute. It's catchy and hopefully people eat it up. The pre-chorus is the hook. It's better than Work Bitch and should get play on pop and urban.
It's not the production I would have wanted. The Invisible Men have their "signature" sound so it's whatever. I don't hear Fancy 2.0 or 3.0 so I'm not really sure why people are making comparisons.
If the song is a success her follow up single (ie the actual song to launch the new era) should be a MONSTER smash. They gotta come hard though.
