Yes I have checked my settings to sync all the songs that are checked. I am on the most recent ios and version 9 or something of itunes. The only way for me to get songs on my ipod right now are to download them on the ipod.
Update the version of your itunes, If I'm not mistaken if you are currently using the latest IOS you must update your itunes to the latest version for it to be compatible, anyways are you having the same problem when syncing photo's or apps?
