REALLY Confused me [detail inside ]

[jojo168]

I usually listen music while I'm on my bed and ready to sleep. But only I could find is that my Zune always remain a low battery in the next morning.
Is there any way to make our Zune auto shut down? Like, maybe shut down 20 minutes late? So that I don't need to shut down my Zune manually?

[Charge]

Just make a playlist thats long enough to make you fall asleep, and short enough to stop after 30 mins, turn off repeat, and the Zune will "sleep" as it has nothing to play.
