how to add song to an existing album in itune windows
I have an existing album ABC, which comes from folderABC on a windows machine. I copied another song XXX to folderABC. How do I get XXX to show up inside album ABC in itune? I tried various things, such as 'add file to library', delete album ABC and re-add folderABC to itune etc.. none of them work. XXX always show up in its own album. I even tried renaming the album name of XXX to match ABC, doesn't work either. Any tips for an itune newbie?
