* When you plug your ipod into your PC, your unit should appear in the devices section.
* When it does, click that and you should see the summary screen for your ipod appear.
* Scroll down and find the "Manually manage music and videos" check box. Check this and confirm your choice.
* Then, go back to your ipod entry under Devices in the tree view and left-click the mouse over the little right-arrow symbol to expand this item. You should then see the contents of your ipod (play lists).
* Click the music list. The songs on your ipod should appear in the list view to the right of the tree view.
* Then delete whatever songs you don't want. This deletes them from your ipod but not from your ITunes library.
Beware however that when you manually manage your music on the ipod, and then you subsequently resume normal syncing operations, any changes you made on the ipod will be lost.
Hope this helps.
