well i screwed up big time. i had a problem with my system, powermac g4 with osx tiger, and had to do a erase and install, problem is that all my itunes were erased , or lost. now i have 500 songs on my ipod nano and im afraid to connect it back to my mac because i have been told that because i have nothing in itunes it will erase everything from my nano. is there anything i can do, can i burn my nano tunes to a disk and reload them to itunes.
