Not good - typical Selena Gomez just.

Apart from the fact that Selena Gomez simply not (!!!) can sing (as compared to the live performances the studio albums have to be very processed) is the song has not demanding - in the chorus "sings" they almost always the same , namely "come and get it".
The rhythm and the video are reminiscent of India.
Overall, not recommended - Selena Gomez might be time to cut a huge slice of Demi Lovato, who can sing very well and whose lyrics deal with emotional, sophisticated topics.
Since Selena Gomez is rather something sure for 6 year olds who have not yet.
