After you have listened to all the songs on your iPod nano, you might want to delete some to make room for new songs. The iPod, a portable music player made by Apple, has a touch-sensitive display and has a capacity of 8GB or 16GB, depending on the configuration. You cannot delete songs using the device; you have to connect your iPod Nano to your computer and launch Apple's free iTunes application to add or delete music.
Launch iTunes on your computer. You use iTunes to play music and manage your iPod nano.
Connect your iPod nano to a USB port on your computer, using the device's included USB cable.
Click the icon of your iPod nano under "Devices" in the left pane of the iTunes application window.
Click the "Music" tab.
Click the "Sync Music" check box to select it. Lists of albums, playlists, artists and genres appear in the iTunes application window.
Click the check box next to each album, playlist, artist or genre that you want to remove, to deselect it and mark it for deletion from your iPod nano during the next sync.
Click the "Sync" button at the bottom of the iTunes window. The songs you selected are removed from the iPod nano.
Click the "Eject" button next to the icon of your iPod Nnano in the left side of the window, and then disconnect the device from your computer.
