The edges of music

What do you still consider music? Is the art released by labels like Mego or Tzadik still music? One of my favourite releases in the style of those labels is the Man'yo album by Yasunao Tone:

"Tone began composing pieces based on overriding the error-correction systems of consumer CD players in order to generate new strings of random digital sound. A pioneer in the use of prepared CDs, Tone first scratched his own self-described "wounded" scotch tape and pinhole-punctured compact disc in 1985."

"The listener is treated to about 53 minutes of sculpted noise in which the recorded waveforms of a skipping CD sample source are contoured according to Chinese symbols derived from Man�yo-shu, an 8th century poetry anthology."

Would you consider this music?

Music is wide open, anything goes.

It is completely subjective.

There is room enough for everybody.
