I can´t see a way to handle this amount of sound files without a descent managing software.

See my response to Tony, I guess I was not very clear but I was suggesting that we could have both.

I don´t see how you could realize the current functionality of storing only one playlist/song no matter how often it is referenced by other playlists.

Quite simple really, a file copy from the empeg to the empeg would create a reference to the file or folder (additional database entry) rather than a copy just like it does with emplode.
