Whenever I try to add my playlist from my computer to my ipod, the crossed out circle appears, and I cannot add it. I found that when I go to my Ipod, the bar that shows how much space is left has a lock next to it. Does this mean anything?
It is in Autosync. Select the iPod in iTunes. Click on the music tab. Select the playlists you want to put onto the iPod. When you wanto add/delete music from the iPod, just do it from these playlists and then sync the iPod.
