Last night I accidently deleted all of my music off my ipod, but the files are still on my itunes library. When I tried to 'manually' move my song files to the ipod, it wouldnt let me. Instead I have to sync all of my songs back on there, but I want to know how to manually do it. I have all of my songs on my ipod now, its just that I need to find where I can manually manage my music on itunes, so I can organize it better. My songs are gray on my ipod library, and I cannot delete some of the songs I dont want.
For future reference, the songs are "greyed out" because you have the iPod set to transfer songs automatically. That is also why the padlock icon appears at the bottom of iTunes next to the space used/available.
