Usher- "All Falls Down (feat. Chris Brown)"

My girlfriend and I played the common game of "Bad, Average, or Good?" when attempting to determine the merit of this song before we heard it. We both settled on 'Average' and then listened to this duet between Usher and Chris Brown. We both decided that the song was pretty good and above our expectations. It's vocally what I expect to hear from Usher, at this point an elder statesman in the R&B genre. And Chris Brown held his own against Usher as well; I would definitely be interested in hearing a collaboration album with these two. But for now, I'll become a little more interested in an upcoming album from Usher. Enjoy.
