Thank you for adding this important point, this is a high priority on my todo list. We have already a basic database of major performers (conductors, soloists, etc...), we just need more computing resources so users can find recordings based filtered by performer. If you've got extra dollar you don't need, consider donating so you can help us with experimenting with features such as this one. But this is a top priority anyway. Thanks again for your feedback!

To add one more discussion of classical metadata, see this from NPR:

Yeah, this. I would totally pay for a high-nitrate, classical-only streaming service that would let you do as you describe, and also things like shuffle by groups, and foreign-language-aware voice search. All the available services are nearly unusable for classical.
