I'll also note that I just sold about 200 classical CDs in Princeton. I went through my collection and took a hard look at what I actually wanted, versus discs I purchased because I wanted to own a copy of the work. With streaming and megaboxes in classical, it's increasingly only worth owning something on disc for fidelity/surround or lack of streaming availability. Given that probably 60-70% of my listening is via streaming in my office, car, or even sometimes at home, it was an obvious choice.
