For me, discovery is the entire reason to use streaming services. I have a ton of hard drive space, and know how to find anything I want to download. I have a fairly large music collection from before the days of streaming. But streaming services help me discover all kinds of things I’d likely never hear otherwise. They still suck, as in they’re greedy as hell and the quality is mid, but I don’t know what I’d do if I had to listen to the same stuff all the time.
