to be fair (and something may be lost in translation) i don’t think folder list is what he’s asking for. What i’d like, and what @R_H_Maasdam is looking for is a way to conduct a drill down search for classical. Arkivmusic offers this, built on the system that powered the old musicblvd and cdnow.
a typical search/browse would look like:
Composer–>Work–>Performance
Performer/Conductor–>Composer–>Work–>Performance
Classical Genre (aka Style)–>Composer/Performer–>Work/Composer–>Work/Performance
this should be easy to do with the data Roon has access to, and if not, there are other metadata sources who can provide this. i built a classical download store with exactly this model…
…in 2003. time for roon to understand how classical aficionados search for content.
