I saw a remark under the Plex Music Goes to Eleven! blog post that mentioned useful features to add for classical music and the poster was encouraged to create a post about it. Since no one seems to have created a post about this, I am starting one. If there is already one that I missed, please direct me to it.
Here are features I would find useful:
Composers
Vocalists
Soloists
Conductors
Orchestra/Ensemble
Period (Baroque, Classical, Impressionist etc)
For tracks:
Major work (eg Symphony No 9, Bergamasque)
Piece (eg 1st Movement, Claire de Lune)
Key
Opus or other identifying number
Does anyone have anything else to add or any comments about the above?
