So i have my music library on my pbook and my ipod is auto synced to it. I bring my ipod to work and connect it to my PC and play the music through windows itunes. I have set the itunes to manual sync so it doesn't clear my music. I read that this will prevent my mac itunes from copying usage stats. How can I fix that? Also, I'm making changes to the songs here on my PC, like changing names, metadata, or even deleting some songs. Is there a way to sync those changes to my itunes and my library? Thanks in advance?
