Hi L. Green,
Thanks for visiting Apple Support Communities.
You can use these steps to set up syncing between your computer and iPod nano:
iTunes 11 for Windows: Set up syncing for iPod, iPhone, or iPad

If you sync automatically, you can choose specific playlists to sync. If you sync manually, you can drag songs to your device.
All the best,
Jeremy
