And of course, by the time you'd read all those cards you would have stopped to do
maintenance on the card reader a couple dozen times.... -- Ian

Assuming a 6MB MP3 file and 40 bytes per card:
6 * 1048576 = 6291456 bytes
/ 40 bytes per card = 157286.4 (157285) cards
* .178mm card thickness = 27996.73 mm high
/ 25.4mm per inch = 1102.233465 inches
/ 12 = 91.85278871 (91.85) feet
