You should check the playback order when the folders have different numbers of tracks.
It seems, that you have some options.
- Apply a proper running number to each track, which can work together with the playback order of the device.
- Put all tracks into one folder.
- Create and use a playlist.
- Study the idiosyncrasies of the player.
Maybe some other Mp3tag user has the best fitting solution for you ...
