Imagine you're like me and only use itunes to put music on your ipod and not use the lame library function you've upgraded to version 11 and found you can't see your shitting songs any more!
Well I found the bastards.
Do this
Open iTunes
Click the iPod button in top right
Click 'on This iPod'
OR
Imagine you are me again and uninstall the fucker and put 10.xxx on again.
You're fucking welcome.
