I just finished it.
It was a really good end. I'm a bit disappointed that there was nothing like this in the game (especially the stuff from 1:02).
The song was good, too. It wasn't great like Still Alive, but it was still a really nice way to end it. There was no funky radio version of it, though
I'm a bit disappointed that it's only 7 hours long, but I've heard the co-op is just as long. I'm yet to start that section of the game.
