Since Justin has disabled comments on his piece "The Machines Stop" I want to ask if any one remembers the short story "Mars Inc." Can't remember the author, but one pertinent bit of imagined future was a pocket juke box that stored (hundreds? thousands?) of songs on a crystal.

I read it not long after it came out. It seemed totally fantastic at the time.

If any one remembers the author post it here.

I will get notified.
