Ok. Here's the way I do it. But it only gets every single song off your ipod or random ones.
Oh yea P.S.: this is for PC, of couse
Make sure your ipod is pluged in and connected to itunes.
Go to:
Start
Settings
Control Panel
Folder Options
View
Hidden Files And Folders
Select Show Hidden Files And Folders
Exit out of everything.
Go to:
My Computer
Name of iPod
iPod_Control (It should be transparent, since it was a hidden file)
Music (Again, transparent)
Now, either open a folder, and click play all, and repeat this for all the files, or highlight ever folder, and drag it into your itunes music, which im not too sure where it is.
There ya go
