all the songs not syncing with my ipod

Try Edit > Preferences > Devices > Reset Sync History (if available) and then try syncing once more.

If that hasn't helped try signing out of the iTunes Store on the device and then try again.

Otherwise see this post on erratic syncing.

Do the songs that won't transfer play in your library? Note you cannot transfer tracks that are in the cloud or come from an Apple Music subscription.
