It is indeed a decent service, and I guess it was worth the money I've paid for it, but there certainly are a bunch of flaws. I miss a lot of my personal music library in it, for example, (and yes, while you can add them, but I pretty much only use/used spotify at work). To be honest, I didn't even remember to enable the HQ option when I had a paid subscription. I also use it on gnu/linux, where the windows client under wine for me is very sluggish (but only at work, not at home), and the native client still has ways to go.
Anyway, I seem to have gotten quite sidetracked, the point I was trying to make is that at least OP is giving them direct feedback and thus an opportunity to improve. While you think it's a great service, surely you can find some ways to improve it? I could, for example, live with a larger cache on the android app so that I can enter a store under ground without the music stopping when the cell service does...
