Can I re-establish all my song library from an iPod or iPhone to a new computer?

Question

I think usually, one iTunes app is associated with an iPod or iPhone, but let's say I got a new computer or installed Windows 7, and now I moved the old computer to the basement, or don't want to boot up the old Windows Vista, or even if that partition is lost, in that case: can I re-establish my song library using the iPod or iPhone that I have?

Because all the songs and videos on the iPod or iPhone is complete, it'd be best if it is possible to somehow re-sync everything to a new computer with the new iTunes app.

Or what if somebody live at home and then have all songs on that computer, and then go to school which is 3 hours of airplane away, or go for a contracting job that also is 3 hours of airplane away, and the iTunes is on the desktop computer back at home... in that case, the re-establishment of the songs can be crucial.

Answer 1

Of course you can. I use iDump for this purpose. iDump can copy all of your MP3s from your iPod to your PC.

iDump will allow you transfer your songs off your iPod to a PC, iDump does come wrapped in installer but you can simply drop the .exe in the root directory on your iPod and run it from there.

Connect your iPod and run iDump and you'll have access to all your songs, select the songs you want to transfer then pick a destination directory and how you would like your songs to be named. And then sit back and transfer all the selected songs to the PC.

Apparently iDump only works for iPods though, and not iPhones.

If you plan to use both, SharePod is probably a better option for you since it now works with iPhones:

Change
Add and remove music, videos, playlists and artwork on your iPod.

Backup
Backup all those tracks you just can't lose onto your computer. Import them automatically into your iTunes library.

Share
SharePod can run straight from the iPod itself, so you can use it at work, school, home - wherever you and your iPod are.

iDump and SharePod are both freeware.
