How to transfer music to my iPod (& iTunes) {click on link}.

Simple technique of Drag & drop the audio file onto the Library icon of iTunes to add to iTunes.

I 'highly' recommend Manual updating of the iPod's playlists. That means you can add songs as you desire, not need to re-do any playlist for the iPod (unless of course that's what you prefer, as otherwise the iPod deletes the previous playlist on the iPod.)
