Sorry, this definitely is stolen.
I'm sorry, but I'm going to have to agree with the others on this one. Number one, the sound quality is terrible, and whether or not you recorded it, it IS identical to the Nintendo 64 version of this game. IDENTICAL. I have the game, trust me. That's the bottom line. You may say you didn't steal it, but its exactly the same. The odds of you actually creating this piece are HIGHLY unlikely, and even if you did, like I SAID, its identical. ;)
