You're welcome, i've wanted to make my playlists load quickly, just sharing the method to other playlist users.
I've also noticed that Mediamonkey can't export M3U playlists with unicode filenames in them properly (the titles are ok but the filenames become something like "???"), so the playlists it generated for my M6 didn't work for my japanese songs. But since i'm browsing the M6's file system directly now, the problem's gone.
