Classical Music Tuning

[featurebase-for-github]

Thanks so much for the app!
As someone who listens to various genres, but also various genres of classical music, I find it a little weird that my clusters are mixing more commercial styles with classical ones. It'd be great to have an algorithm that's like “choral music," “Opera," “symphonic," etc. based on well-established sub-genres of classical music. You may find inspiration from the classical music streaming services and how they curate listening to new music.
Thanks again!
