I think you should compare disc access time to your getting up, hitting 'open', pulling out one disc, putting it into the case, putting the case back on the shelf, pulling out another case, taking out the disc, putting it in the player, and hitting 'play'.
We're you able to do all this without turning on any lights? Oh, yes, one more thing: go sit down again.
