Composer list in library browser

[rhizomusicosmos]

Would the Genre tags be enough to provide that separation? Otherwise some way to parse the library import, e.g. a target directory could be ticked as "contains classical content" when adding it as an audio source. This would mean the user would need to keep all "classical" files in a separate folder or drive to other "popular" content. This is not so different to the "Movies" and "TV Shows" separation that Kodi uses in order to scrape appropriate metadata.
