This is fantastic, classical music absolutely needs a dedicated interface since the organization by composer and multi-movement works is so different from popular music. But I wonder if it will help with finding which version of a work to listen to. A given symphony or piano prelude might have 100 or more recordings. If you go to classical music forum postings, you can usually find a thread asking "what's your favori…
So this is true for how people organize popular music, but I can't help but think the classical music model is better and even pop music fans might benefit from having an information model for their music that is more in line with how classical music is organized.
Pop music seems to short-shrift the songwriters and other people who work in the background (at least when it comes to credit, if not always money). And some live-music focused acts, like jam bands, would probably seriously benefit from tracking performances in the same way. I know Phish fans, for example, usually end up tracking their favorite recordings, performances, and dates by filename in similar ways to classical music fans. And the models used by standard music and streaming applications don't fit them very well either.
