iPod touch will not sync
My computer recognizes my iPod when I connect it. I have auto sync selected. It goes through the motions of syncing but the new songs i have uploaded will not sync. They are in my library and I can play them. Under "on my device" in music, the songs are there but they are grayed out. I have shut down computer and iPod, unauthorized and authorized my computer, and tried to drag songs manually. I have the latest version of iTunes and my iPod says the software is up to date. Any suggestions? Thanks
iPod touch, iOS 6.1.6
