If your computers are connected to your home network, you can use music sharing to listen to music on another computer. But if you want to copy your music to your laptop, for example, and your computers arent connected to your home network, you can use your iPod or a removable hard disk to quickly copy your songs from one computer to another.
When you move music to another computer, youll need to authorize it to play iTunes Music Store purchases. Just enter your Apple ID and password when prompted. Check out our topic on Authorizing and Deauthorizing Your Computers, for more information.
If you have space available, and you want to use your iPod as a removable hard disk to move music and videos to a new computer, start by connecting your iPod to your computer. Select your iPod from the iTunes Source list, and then click the iPod Options button. Click the "Enable disk use" checkbox, and then click OK. On a Windows computer, find your iPod listed as a drive under "My Computer." On a Mac, find your iPod in the sidebar of a Finder window.
When youre using your iPod as a removable hard disk, and you need to make room so that you can move more songs and videos, youll need to set your iPod to manually manage songs and playlists. With your iPod selected in your iTunes Source list, click the iPod Options button. Make sure "Manually manage songs and playlists" is selected, and then click OK. Now you can remove the songs you want, in order to make space. When youre done moving songs and videos, you might want to go back to iPod Options, and set it back to "Automatically update all songs and playlists."
If you want to copy your playlists to another computer, along with your music, just go to the File menu and select Export Library. Type a name for your exported library, save it to your removable hard disk, and then click Save. Now connect your removable hard disk to your new computer and open iTunes. From the File menu, select Import. On a Windows computer, select "XML files" from the Files of type menu, and then locate the exported library file on your removable hard disk. Click Open, and all the playlists on your old computer will be copied over. If some playlists were duplicated, just select the duplicates, go to the Edit menu, and select Clear.
