If bliss finds playlist files (*.m3u, ...) Playlist based Rules -> see Details
*Rule to move them to specific path
*Rule to update them if needed because other rules changes something
-> like renames or move files
*Rule to General try to fix them (search best matching files in bliss and correct the playlist file entry to the found file) -> this should be made manually but bliss can suggest the entry
The first point may mean the playlist has to be edited, if it's using relative paths.
