Have a Timer so it records later while I am out (if I leave PC running).

Leave the PC running with a streaming audio, particularly a radio station stream.
Later, while I am out, when my friend's radio show comes on, the Timer starts recording it.
The next day I can listen to my friend's show (he lives in another state).

Of course, I'd need to disable the Screensaver and possibly switch off the screen as well?
