Synchronize Entire Library Only Copies Files From Playlists

[Raziel]

For some reason, when I synchronize my device using MM 2.5.2.951 it only copies files to my device that exist in a playlist, even if "Entire Library" is selcted under the plugin.

While this isn't neccesarily undesirable behaviour, it does seem to be contrary to the selection of "Entire Library".

If anyone can fill me in on how this works / should work, it would be greatly appreciated.
