how do I sync multiple devices
I have an Ipad 64G, Ipod classic 160G, Iphone 32G and a nano 8G. I have 80G of music in my library. How do I manage my music between devices? When I sync my iphone I check the music I want and sync......no problems. On my 160G Ipod I want all of my music so I check all of the music and sync........no problems. When I want to go back and alter my music on my iphone or other devices all of my music is check so when I plug my device in, it wants to load all 80G of music and of course it won't let me. Now i have to go back and uncheck all the music that won't fit. As you can see with evertything froma 8G device to a 160G device this is a pain in the ***!
