Was it on purpose or an accident? Be amazed...
Heres a video showing the trailer for Legend of Zelda: Skyward Sword. First it plays it regularly then backwards. See if you can catch what song it is when reversed.
Did you hear it? ZEDLA'S LULLABY FROM OCARINA OF TIME! I didn't expect that, pretty insane. Heres the lullaby if you don't remember.
Cool little things like that are always cool to find out. Don't know if something that cool was an accident. Secret fanservice maybe. Did that put a smile on your day? Leave a comment below.
