Actually it seems the entire music industry including the distributors don't want sales - they seem to prefer streaming.

I remember when apple music came out and I couldn't listen to my music anymore

Apple seemingly did some screwy things with Apple Match and so forth and I've had to fix up some things in my library as a result. (I actually have a batch of CDs I need to re-rip.) But what's there today seems to work pretty well separating what I have my own copies of vs. what I only have available via Apple Music.

Though maybe you're saying something differently.

I think the music industry is perfectly happy to sell you music at $1/song and even physical CDs if you like. It's just that, for most people who don't already have large curated collections, it apparently makes sense to subscribe for $10/month rather than buy albums for $10. For me it makes sense to subscribe and occasionally also buy something to add to my owned collection.

I believe when apple music came out my music disappeared and I never put music on my phone since. (I just used a usb stick in the car from then on)

I think the music industry doesn't care anymore about selling music - why sell you a song for $1 (that you might copy for your friends) if they can sell you the same song again and again every month?

Bandcamp admittedly exists to be an exception to this rule, but yeah, they're definitely a buy-music-oriented platform. They're also the most artist-friendly platform there is (among other things, they've been doing "Bandcamp Fridays" all this year where they've foregone their cut of sales to help artists make it through the year).
