[Tutor] playing mp3 files

Fri Dec 21 00:46:15 CET 2012

the robotradio program is coming along. It plays. it dances. it sings. 
IT selects random libraries and random broadcast files. and it restarts 
itself with consummate ease. Aka, NOW wtf?!? Jim is exchanging letters 
with me on this, but does not yet have a solution.

Here's the code of the hour: BEWARE WORD WRAP!!!
