well, I think autechre's point may very well be to question the idea of "meaning" as a human construct. We assign meaning to things based on our own, or on shared, experiences and beliefs. Does anything have meaning beyond our own pretensions to assigning meaning? No. A computer does not operate in the realm of symbolism and associative imagery. After all, if someone names a track "green pen" another person could think of all sorts of meanings, and maybe the artist would say something flip like "whatever you want it to mean is right" or they might say something literal, like "oh yeah, I used a green pen to write down the chords for that one" ;-)

It's just sometimes cool if there WAS a source or inspiration for the names that artists use for their work. It can give an insight into their intent with the work. Or it can be distracting I suppose.
