Feasibly, you could attach your player once, let emplode get the database, then unplug it and deal with your playlists in emplode as long as you don't exit the program. emplode doesn't touch the empeg except for downloading its info and synchronizing.

Then again, I could be wrong. There's a serial number of sorts that prevents intersecting syncs that could make that not work. It's possible that there are other things, too. But you could give it a shot.
