One way you can do it is to have musicmatch jukebox watch the folders you save your music to, then when you open jukebox it will automatically scan the folders and add any new files to your library.
Open jukebox and on the toolbar go to File>Watch Folders> then click on "Add" find your shared folder, hi-lite it then click ok. The default location is for your shared folder is C:\Documents and Settings\"your account name"\Shared.
I'm not for sure this is what you meant? Post back if not
