You can fix a frozen iPod fairly quick. All you have to do is hold the menu and action buttons until your screen goes black. The top button on the click wheel is the menu button and it says menu. The button in the center of the click wheel is the action button. When you hold both of those buttons the screen goes black after a few seconds. What it is actually doing is restarting the iPod. It will take about 55 seconds for the iPod to reboot and when it does it will work fine again.
