Watch below for the video. From what I have read, it may be a bonus on the Step Up 2 The Streets soundtrack.

The video version is a bit different from the version of the song that was circulated (it's in our audio player). The song in the video features a piano introduction from Ryan Leslie, who is featured throughout the video. Looking at the shots from the video and the trailer, I noticed you can also see him in the trailer at the 25 second mark, so this must have been shot a while ago.
