I heard this song a few weeks back....John Legend performed this with Juanes at the NBA All Star Game. I have since added it to my iPod and have fallen in love with it. It gives me chills. It gives me inspiration. It was an excellent addition to my run today.
(No surprise, but I'm late to the party, as I found it was also used throughout the Obama campaign too....democratic convention, etc. Hmph. Ah well, better late than never.)
