Apple have unhelpfully created two "iTunes":
- iTunes - the programme on your computer
- The iTunes Store - the online place where you can buy music that many people refer to as iTunes. The store only knows about the music that you have purchased from the store. It does not know about your music from CD or anywhere else (unless you use the Match service, which I assume you do not)
To get copies of the music that you obtained elsewhere onto another computer (and then into that computer's iTunes), you need to copy the music from the old computer to the new one.
