Local SSD

Plex/Plexamp/synfonium + Tidal + QoBuz + Bandcamp

If you care about artists not being screwed over, Tidal is usually the first recommendation.

I use a combo of streaming stuff I bought on Bandcamp with their app and playing local files. In addition to albums and EPs, I have bought a lot of singles on Bandcamp. I put all the singles in a giant constantly growing playlist on the Bandcamp app and then set it to random shuffle. It takes more effort than using something like Spotify, but I personally like it a lot more because it's only full of music I know I like and I feel satisfied because I supported the artists I like.
