Hi.
You may transfer the Songs from the Computer to the iPod Device by using the iTunes Application.
However, please feel free to contact for further information about the Application and the detailed steps to transfer the Songs.

hook the ipod up to itunes and when it opens to the page that you see the picture of the ipod. put a check mark next to the automatically sync my ipod.
However, if you have other song on your ipod that are not in your library they will be delete during the sync.
No here is the best way to do it.
put a check next to manage music manually, instead of syncing it.
find the music file folder on your computer, open it up and minimize it.
open itunes and click on music under your ipod. now maximized your music folder and drag the songs into the white area with all the lines. the songs will load onto your ipod.
do only about 100 or so at a time to avoid problems.
to get multiple song click on the top song, and press shift and highlight the last song this will mark all songs in between to be moved. now drag the highlighted songs and watch them load.
