I can't take the time for absolute verification right now but:

1.Connect your ipod to computer
2. Hit up Itunes
3. Hit Edit tab (upper left)
4. Hit Preferences
5. Hit Ipod tab

There should be check boxes for what you prefer. I think the word "automatic" is in one or more boxes. If this is unclear, email me at goodkid1yahoo.com and I will do it right for you after performing the steps myself, for a memory jog.
