In the past, technically savvy music nerds like me had options. LPs and CDs as a distribution format offered true permanence. Vinyl when cared for properly usually outlives the owner. CDs can be ripped and archived with perfect 1:1 accuracy.
These formats don't disappear from my record shelves at the whim of an executive or a change to a silly end user license agreement. They're mine forever, for me to cherish and learn from for as long as I want.
Until the music industry offers this type of solution for the digital music ecosystem, they will not be adequately serving music's most dedicated and passionate patrons.
Bandcamp is the only service that comes close to delivering the proper solution. But they are so uncompromising in their ideals that the 'industry' will not work with them. It's too bad, because they and DistroKid are the only two online music industry services I have ever seen that are genuinely interested in furthering the lives of their users.
LPs and CDs still exist.
"so long as you keep all your discovery of new music within Spotify - because you'll never discover what isn't there."
This is exactly the reason we have arguments about the importance of net neutrality - which your underlying point is arguing directly against. Not sure if that was intentional or not - but the music industry is a really bad measuring stick of success in this area.
To contrast to Spotify - I'm sure Disney would be fine with it if everyone watched what they were hosting on their network exclusively and ignored the content on other platforms.
On a side note: Isn't this basically what Disney Life is already? Did I miss something?
I wasn't trying to make an argument either way on what's good/bad with Spotify (or any service large enough to be used as an only provider) but my feeling of missing out on something is something I try to avoid more than actually missing out on something (if that makes any sense). A kind of loss aversion I suppose. Bryter to have less and not know, than have more and see what you are missing.
Classical is a bit special, but hopefully efforts like the internet archive can help bring at least a lot of the royalty free music to streaming.
I'd be perfectly happy with a streaming service aggregating the current top 10 services for tv/movies, and I assume 90% of customers would. It seems reasonable to make a product that caters to "most" rather the all customers, just like Spotify.
