I have the remasters of the NIN albums, big whoop they are, also including 5.1 offically released concerts I own, only the first 3 channels are needed, the last 2 channels are ONLY used for crowd noise. @Hexter: Because Thompson wants to commit towards MP3, even with it's MP4 sucessor they still believe MP3 has more benifits over it's newer incarnation. MP3 is too old now, as we find better ways to improve upon it, the quality loss will be too great by then seeing on how many frequencys we keep messing with so that the average human ear can't tell the difference between a 320 KBPS mp3 and an actual audio CD.
