Why don't new songs purchased on I-Tunes synch to my iPod (Nano 5th generation) that is recongized by my computer? What do I do to make that happen?

Question

I purchased a new desk top computer. My iTunes account is regognized by the new computer, but only includes the songs purchased on iTunes. My iPod is also recognized by the computer when I plug it in. When I attempt to sync new songs purchased on iTunes to my iPod, they do sync to my iPod. Can anyone help me figure this out?

Answer 1

There are two questions here...  Your computer has an iTunes library, not an iTunes "account."  The account that relates to iTunes is your Apple ID, which you use to make purchases from the iTunes Store.  Signing in to the iTunes Store using your Apple ID does not put your songs from your previous iTunes library (on the old computer) into your new iTunes library.  You need to transfer your iTunes library from your old computer to your new computer.
NOTE:  If you happen to be subscribed to Apple's iTunes Match service, your entire iTunes music library is stored in iCloud, and you CAN access it from any supported computer or mobile device, using your Apple ID.
If you have access to your old computer and your old iTunes library, and you want to transfer it to your new computer, you can post back to get more info on that topic.  For songs that are previous purchases from the iTunes Store, you can re-download them into your new iTunes library at no cost, by signing in to the iTunes Store (using the same Apple ID) and going to the Purchases screen (click on Purchased under QUICK LINKS on the iTunes Store Home screen).
The second separate question is about setting up automatic syncing for the iPod, from your new iTunes library.  You may not want to do that until you have all songs from your old iTunes library consolidated into your new iTunes library.  Please post back...
