IPod touch cannot be synced error 13019. What do I do?

I manually manage all songs and info on the ipod touch. Nothing is selected to sync automatically. I have no voice notes, there are no podcasts, only a bunch of songs I'm trying to put on my ipod. When it is plugged in, it shows up under devices in the sidebar. I click and drag the playlists/individual songs I want to add to the ipod, and they appear under the name of the device in the sidebar. I then get the 13019 error message, and even though the songs or playlists appear when the ipod is plugged in, they do not appear on the actual ipod device. I have no voice notes or podcasts that could be messing with it - deleting these and resyncing have been the solution I've seen most often. Any advice would be greatly appreciated.
