Name That Tune!

You may notice that there is a song playing in the background of my blog. If you want, you can pause it, it is on the left. I had this idea where I can replace a different song I like on the blog every once in awhile and see who can figure out what song it is. Just comment in the most recent post to say what song it is if you know. I'll keep track of who figured out the most songs. Today's song is really easy, I'll give you a hint: It's really freaking long.
