And by the way, to be clear...if the Empeg had a so called "deep copy", then I don't think it should actually make a second copy of the underlying MP3 file. It should make a copy of the reference to the MP3 file...just as if I had dragged and dropped the Tunes themselves and selected "copy" from the pop up menu...

Essentially...deep copy should do something very similar to what happens now...create a shortcut of the item being copied...but...don't stop at the top item....recursively go down the tree and make shortcut-copies of everything below it...including new shortcuts for the tunes at the bottom of the tree...

You still just want one copy of the song on the player... But if I want to copy a folder tree (and all of its underlying folders and tunes) to a new location...I want to actually COPY those shortcuts...not just create a shortcut to the top level folder that basically references to same tree from the next level down.
