Classical isn’t harder. It’s just so niche that leadership at spotify never bothered. It has a whole different taxonomy; it’s composer, not performer based etc.

Spotify isn’t against new taxonomies outside of weatern pop music. The India launch, where ragas were super important, shows it. But the Indian market is vastly larger than the small (albeit loud) number of classical music enthusiasts.

All that is to say, it’s a business decision, not a tech or AI problem.

(I really like classical music, too, btw., so please don’t read this as me not respecting that user base.)
