Rather than recording this in-game, which, without perfect playing will add distortion effects on death, the song is inaccurate, and will depend on the quality of however you are capturing the audio. Using a USB and my Xbox, I copied over the game, used a program called Velocity to extract the contents of the music folder, and then used another program called vgmstream to extract the different sounds used to create the music, putting these into audacity brings the song back together, in perfect quality!
