When this is complete, you will see this iTunes-like window that lists the content of your iPod.
From here you can do a few things:
- Listen to songs on iPod (this is useful if you're planning to just copy a small number of songs from the iPod, rather than all of them
- Choose what to copy (your options include just music, just video, just MP3 files, just AAC files, etc.)
Most people will choose to transfer all iPod data.
