One, the vocals feel very one John Mayer. There isn't a hardness to the vocals, and the range is lighter and higher. For folks that loved "Continuum" this is probably going to be right up your alley.
It also strikes me as a much more pop-based song than I like to hear from him. I feel like Ryan Tedder could have had a hand in the songwriting process. That said, for me that's a little different than previous Mayer music.
Overall opinion is that I like that John Mayer can change up thigns just a little bit, and much like the song says, continue to grow and change as a musician.
