I’ve been using foobar for like twenty years (outside of a brief Linux only period where I eventually settled on deadbeef). I don’t mess with iTunes so I also like the iOS version of foobar for both having its own easier to use music folder and for being able to play network shares. I have a couple large thumb drives filled with music plugged directly into my router. My one complaint is the iOS version doesn’t know how to handle disc numbers for double albums, so the way out is through will follow somewhat damaged and whatnot.
Outside of that sort of diy home streaming I don’t fuck with any of the streaming services.
