good story.
what's ironic though is that its now reasonably well documented that

if the disk drive is in the line of fire when they start to play loud,

it really will be unable to keep up. this has nothing to do with bit

rates, but is (probably) caused by the the vibrations causing read

failures which necessitate a lot of retrys, thus slowing down the

effective streaming bandwidth of the disk. if the disk is kept out the

way of direct incoming sound, the issue goes away.
yes, really!
