My personal answer to this question would be an unequivocal: don't.
MusicBee was designed (same as other music managers) to make use of the near endless possibilities that metadata (tags) in music files can offer.
So it is essential that a user makes sure that his files are properly tagged with at least the most essential tags.
But once in a while there will be a user trying to find refugee from music players such as WMP, does not care about tags, and just wants MusicBee to act the same as WMP or some other more basic file/folder player.
It won't and it shouldn't.
MusicBee is an advanced music player/manager.
Users that persist in trying to do this but fail and start complaining will often get reprimanding comments about what they really should do. (look for some simple music player)
But such discussions do not improve the quality or the atmosphere of such topics, and usually don't end well.
So on this Saturday afternoon I was thinking: why not have a dedicated topic for users that want to persist in using MusicBee as a file/folder player.
If only to possibly bring some relief to other topics that are spoiled by people that shouldn't be using MusicBee in the first place for this particular reason.
