Login to your computer and launch iTunes by clicking the shortcut icon on the desktop or from the All Programmes menu. To make sure that iTunes works perfectly, it would be best to close all other applications that might be running on your computer.
At the top of the iTunes window, you will see a toolbar with numerous buttons; click the ‘File’ button from the toolbar. From the list of options that appears, choose ‘Import’. You can also open the ‘Import’ dialogue box by simply pressing the Ctrl, Shift and O keys simultaneously on your keyboard.
A list of all the playlists that you ever exported to your iTunes account will be displayed in the ‘Import’ dialogue box. Look for the desired playlist. If you have a very large number of playlists in the account, a possible way to save time looking for a particular playlist would be to press the letter key with which the name of the playlist you are looking for starts. For instance, if you are looking for a play list that was named ‘My Favourite Songs’, press the M key on your keyboard to make the search easier.
Click on the icon of the playlist you wish to restore and then click the ‘Import’ button on the ‘Import’ dialogue box. Repeat the same process for restoring more playlists if desired.
