Egad, Ken_Fallon, I have to say I strongly and FUNDAMENTALLY disagree there.  I guess I'll HAVE to record a followup now...

Wait.  That was your plan all along, wasn't it? You sly devil!

Your argument essentially goes to the point of opposing local storage of files or information at all. What you're describing sounds like the user just has a big literally-meaningless (locally) number, and his/her/its media player is meant to send that big meaningless number to one or more places scattered on the general internet to beg for relevant "content".  (Your description doesn't take it that far, but once you're down to nothing but an audio and/or video stream and have gotten rid of everything else meaningful, and have mandated an internet connection to get it, why even keep the media itself locally?)

I'll save the rest for a followup episode, so you win this round. :-)
