I need to disagree with this....yes, I agree that people can be TOO picky about sound quality, but I also want to make this point:

The composer did not intend his/her music to be recorded on sub-standard equipment and heard on inferior systems. The point of composing the music is surely that it may be heard as the composer intended? With the sound quality that he wanted? Without using a full orchestra actually in the Cinema? I'm sure most composers did not WANT the hiss or pops when they were composing or conducting the orchestra/band, so why should the score not be honoured with the best available sound quality that can be offered at the time? I am fully in favour of "Digitally Re-Mastering" and CD Noise reduction etc etc because the music turns out the WAY IT WAS INTENDED TO BE HEARD....

There are exceptions to this - for example the original Sondtrack releases to Star Wars (Episode IV, if you will) had a distinct sound to them, as the music did in the film, which has disappeared somewhat on more recent releases after it has been tinkered with....

.....but in general - I LIKE listening to the music the way it was intended...
