Al, you're right--Samba is how e-smith does the windows file-sharing. It seems, though, that most of the responses are referring to the jukebox blade, when there's no need to use it here. Just set up an ibay and double-click on the files you want to play. Simple. The jukebox is cool, but not really needed here.
Merlin, the procedures for making and using i-bays are discussed in some detail in the manual, which is available here in a variety of formats.
