Dang new gadgets! Ipod help

One mehtod is to hold down the power/sleep/wake button and + volume button until the apple logo appeared (approx 10 seconds).

A screen will pop up with what looks a little like system settings in yellow text (similar looking to a DOS/shell command screen)
Then press the sleep button and the screen turns off.
Then press the sleep button again and the iPod starts as normal and the songs and playlists should work as usual.

If this doesnt work then do a back up and check link below to try other stuff
