There are a smattering of different remixes out there, but it doesn't matter, they're all good because they all have the vocals, the piano, and the beat. This is the original.
There are two very ironic symbolism's pertinent to me in the video that I had no idea were there till I found it to post. I'd be shocked if anybody other than maybe my brother can get both. I got a good laugh though.
Find the long version on iTunes it's incredible.
And yes I realize it came out in 2008.
