Here's an example of how amazing the internet can be. So a group of us Sasuke fans started to notice that a lot of the music used on the program sounded familiar. Most obviously to me was the ending credits song: "Victory" from the Naruto soundtrack. Not too hard for most to identify since Naruto is one of those mainstream anime series. But then things got harder.
"This song sounds so familiar, but what is it?! WHAT IS IT?!?!"
"Oh, I knew I heard it from somewhere. It's from Chicken Run ."
Then the pool of knowledge dries up to puddle size: "What is that music that plays when the camera pans over Stage 2's obstacles during Sasuke 22?"
What the fuck, right? That's almost an impossible task. How the hell am I supposed to find that straw of knowledge in the haystack of all the music ever created? Well, damn, Internet to the rescue! Lookie here, someone comes in and tells us that the song is called "Operation Room" and it comes from a PS3 game called Mobile Suit Gundam: Target in Sight, a.k.a. Crossfire in the U.S.
Without this "internet" thing, how would i have found that? Asking my family members? Neighbors? How far can I reach from my chair? Across the world, apparently. (^___^)
