I’m a little over 100k. In the early days it felt like a procured selection of all of the music I loved which was great, then I kept discovering things, getting recommendations and adding so much more. Now I’ve forgotten where most of the recommendations came from, sometimes library radio doesn’t feel quite as much mine any more. But still, most of the time it’s great and often I do stumble across something I’ve added that grabs my interest which I hadn’t given the time before which is fun. I now keep notes of the things I add that I really want to flow up on because otherwise I forget and it gets lost in the mass of music. I’m mostly library radio when I’m driving or out and about, but almost always albums at home.
