Hey cindylouwho8,
We're grateful that you posted here so we can help you figure this out.
We think that the best course of action here would be to remove the songs that you synced and try syncing them over once again. To be sure that you are following all of the recommended steps to successfully sync content between your PC and your iPod, we would recommend following along with this article when you go to sync those songs over again: Sync iTunes content on PC with your devices - Apple Support
We hope this does the trick for you!
Cheers.
