Resume iTunes Music even in Sleep Mode

"As other people here have said, sleep suspends the computer and (that's why you hear the fans and drives turn off — it's using very little power), nothing can keep running.

If you are running Leopard or later, you can press ctrlshift⏏ to turn off the display.

I've also put together a couple of tiny applications that you can use to turn your screen off.

Zeez sits in your menu bar
sleepscreen is a command line executable (so you can call it from scripts and in other creative ways)

Both of those were put together a while ago for my own amusement, so don't expect much (but do tell me if they're broken for you)."

"The whole PC goes to sleep, not just the monitor. The hard drive turns off, wireless turns off, everything; this makes it impossible to play any music.

To only turn off the screen turn the brightness all the way down; the lowest level will turn the backlight off (at least that's what happens on a 2007 MacBook)."
