I have an ipod and it definitly didnt need an UUID to play anything last
time i used it ... (otherwise ffmpeg would support generating such UUIDed
files already ...)
Though its likely not the newest firmware, guess its a new feature ;)
One of these criminal lock in attempts which are all so common these days.

And iam not planing to upgrade the firmware except to something linux
based maybe ...
But then iam not really using the ipod and its misdesigned 5 rotten apple
button looserinterface is really not something with which it could be used
anyway.

It is not what we do, but why we do it that matters.
