iproblems

Can anyone tell me if it is possible to transfer my data from my ipod to any type of file so that I may reinsert into Itunes. i have lost my song file within itunes and the library now only exists on the ipod itself, I can not sync from the pod to the itunes library so my thought was to create a download from the pod to a removable file then insert that way................anyone have any experience with that concept??

thank you
