Go to iTune's menu File>Add to Library... then direct it to your LW Download folder & select the songs you want to add. Press add. You can add multiple songs at once by holding down the SHIFT key at the same time you are selecting. (The keyboard shortcut is to hold down Control & O keys to add files.)

Normally this would be under:
C:\Documents and Settings\"your account name"\Shared
