The author goes on a lot about metadata and bad search interfaces for it. Yes, classical music metadata doesn't fit with the "simple" pop music artist/album/song format. (Though the "featuring" and remixes in pop music also mess that up.)
Often people try too hard to fit data into a fixed schema or ontology. It made sense when data storage and retrieval was based around tabular and relational data, but in these days of search engines and document databases and JSON, it's just unnecessary. Instead of pre-determining the fields you search on, you should search with free text, then refine with whatever metadata happens to be available.
So instead of messing with Spotify's "artist" search, you could just go to Amazon (or Google) and type in "Beethoven's Ninth Bernstein New York Philharmonic" and you'll almost certainly get back the items you want near the top of the list.
