You're probably wondering what the S stands for. Silent is a good guess, but the actual word is Silenced. When I first uploaded this video, I learned that SME had chosen to block videos using it in order to enforce their copyright. I disputed the decision on Fair Use grounds, and for about a week, the video was viewable. Since then, SME has rejected my dispute, and re-blocked it.
Well, that's their business, I suppose, although I don't understand why the audio wasn't just muted as I've seen happen on other videos. So, because I want this video to be posted, and because they clearly want their money, here is the video WITHOUT the music. Instead, I'll leave the iTunes information, and let you decide if you want to buy it and listen to it alongside the video. Your choice.

PS: The video looks absolutely ridiculous without the audio. Please, if you don't want to go to the trouble of getting the song, don't bother watching the rest.
