Skyward Sword Trailer Easter Egg

Lately, news has circulated the Internet that the Legend of Zelda: Skyward Sword trailer contains an Easter Egg. When played backwards, you can hear Zelda's Lullaby.

Here is the original trailer.

Here is the audio track reversed.

Because I own the Ocarina of Time soundtrack CD, I took the real Zelda's Lullaby track, reversed it, and replaced the video's audio track. It's amazing that such a slow song could be remixed into an action song.

Although this was an Easter Egg for Zelda fans, there are always ways to overanalyze it.
