I have a big music library. Nothing special there.
But I very much dislike the way usually music library is displayed in most recommended players, according to Artist/Album/Year/Genre tags, ignoring my folder structure or making it hardly accessible.
The problem is that not all my music is tagged according to genre etc, but all is perfectly ordered by folder structure which takes into account all characteristics handled by tags, as well as many others, which I can change and specify at any time. (I can decide ordering my music by country, inside a sub-category like "baroque music", for example).
The advantage of using folder-structure-display of medialibrary is that all the logical structure is displayed, with all sub-categories, which can be sub-detailed, varied, and changed at wish and be all visible at the same time.
I am looking for some plugins to good players that would provide a solution to this, and I am looking for different solutions to this.
Therefore I'll display as my own answer some solutions that I have already found and welcome other answers with new and better ways to achieve the same purpose.
(Most welcome are of course players that, beside having the capability discussed here, would not lack other elementary features like playlists in tabs, search, and the like.)
