iPod Nano freezing

I have encountered in several situations where my iPod nano would just freeze and you could do nothing to get it rebooted or whatever. Is this happening to you? The first time it froze, I had to wait until the battery runs out but now I have figured out a way to restart your nano.

It's quite simple really

Press the middle and the menu button at the same time for a few seconds and your nano will soon restart. lol. That's it! simple and no more worries...
