Not only is it a pretty great song, this video is pretty cool. It's almost more of a documentary about finding love than it is a music video.

The video follows the story of a man who proposed to his girlfriend on a New York subway train, with a Justin Timberlake song playing on his phone.

No one knows who this couple is, and the documentary crew seeks to find them in the video.

Such a different kind of music video. Like I said above, it's more of a Youtube documentary than an actual music video.

I won't spoil the ending for you...
