Yup. What I really want is to be able to browse by composer, then work, and then show me all the performances (regardless of whether a whole album or part of an album), and let be sort/filter by popularity, trending, new, and performer.

I'm honestly pretty surprised the metadata problem hasn't been solved by now. Even if the labels are providing it in an inconsistent format, cleaning it all up to 99.9% consistency seems like it could be done fairly efficiently. The universe of the names of classical composers and performers isn't that large.
