"Fyrus - The Legend of Zelda: Twilight Princess" is a high quality rip of "Fyrus" from The Legend of Zelda: Twilight Princess.
The rip skips the intro and goes straight to the battle portion of the track. The tempo has also been slightly lowered. At 0:54, a portion of the melody starts looping over and over for the rest of the track, with the voices of the choir progressively lowering in pitch with each loop.
The GiIvaSunner upload of this rip used the current name. The SiIvaGunner upload, however, was originally named "Fyrus Battle - The Legend of Zelda: Twilight Princess".
