I think it's important for people who love music to retain physical CDs or even vinyl, because it sounds so great and so much warmer than music over the internet.
Realism is always subjective in film. There's no such thing as cinema verite. The only true cinema verite would be what Andy Warhol did with his film about the Empire State Building - eight hours or so from one angle, and even then it's not really cinema verite, because you aren't actually there.
