You must drag it back onto the iPod via iTunes when your iPod is plugged into the computer.
To delete updates on your Ipod, you will need to move all of the music onto your computer and then manually reset the Ipod back to factory settings. When you hook the Ipod back up to the computer, do not update it and just add the music back.
