You guys are kidding me, right?
The "spoiler" song was in a trailer everyone's seen. Everyone's heard it. If you don't wanna listen to the full version, then just don't click on the video, but you already knew the song was in the game. I just posted it there to show that the leaks have indeed begun, and soon there will be actual spoilers out.
