Wow. Great in HQ. Gets even better after a few listens.
Which songs click with which people is obviously going to be subjective. I think it's great that she's playing around with her sound and yet going back to more of a classic feel (vocally speaking.) Honestly, the thing that has drawn me in the most with all 3 of the songs is her vocals. I think she sounds great. That unique Britney tone and willingness to experiment with it in the studio is what is awesome about all the songs we've heard so far.
Pretty much exactly what I was hoping for (album wise.) Can't wait to hear what's next!
