When I got my new computer, one problem I faced was getting my music from my old computer to the new one. I should have backed up my music onto a flash drive, like I did with my pictures and other files but I didn't.
When I plugged my iPod into my new computer it wanted to erase my iPod and replace the files with the music I bought from iTunes but not other items on the iPod. That is fine but I had music (mostly kid's stuff and mediations) that came from borrowed CDs. I found lots of downloadable programs to transferthe files but here's the tutorial I used to manually moving files over.
