There is probably an easy answer for this but I am at a loss right now. I had to reinstall the I Tunes due to a computer crash and I wanted to preserve the songs already on the Ipod. THe problem is that I can not update my Ipod with newly douwnloaded songs, and the old songs are only visible on the screen in light gray . Is there any way to merge the new downloads with the old library of songs already on the I-pod. I do not want to erase them and start from scratch again. Please help.
