I like it... but it took me a few listens to decide that. I didn't like it at all at first, but around an hour after I heard it I had the hook in my head, so I listened again, and thought it wasn't that bad.
The one issue, and I must stress that I have no issue with popstar vocal abilities, is that the obviously high level of autotune makes it seem like she can't sing. A portion of modern pop songs do go for an "autotune as art" element (Britney, Kesha, Katy, Rihanna) on dancier songs, but this seems excessive and isn't helping her against the people who question her talent.
6.5/10, at the moment, it might increase a little once the video arrives.
