Yeah I think that the general numbers are a huge tent, and useful for talking about industry-wide trends like "most people would get the album on iTunes rather than buying a physical copy", whereas a niche genre like ours has it's own trends for sure.
And while I absolutely agree about big-box stores that stock records (or, depressingly less and less, actual record stores), consider that in many of the threads that deal with cast recordings on these boards you find people talking about their pre-orders from Ghostlight or PS Classics and rejoicing when their copies arrive.
I personally use Spotify mostly, and purchase albums I want to take around with my in my iTunes library. But Spotify users are still a minority among listeners, and the theatre crowd is generally much older than the average streamer.
Lots of interesting crosswinds in the variables here.
Words don't deserve that kind of malarkey. They're innocent, neutral, precise, standing for this, describing that, meaning the other, so if you look after them you can build bridges across incomprehension and chaos. But when they get their corners knocked off, they're no good anymore…I don't think writers are sacred, but words are. They deserve respect. If you get the right ones in the right order, you can nudge the world a little.
