Interesting take that choice with music is the toughest hurdle. I run into this all the time on Google Music. I open the app and I want to listen to something. I can choose a list of things I've heard recently (nice because I like to listen to albums), but when I'm not feeling my recent additions or plays, I'd like to deep dive into my library and listen to stuff that I haven't heard in a while.<p>There is a heavy focus on "what's new" but in reality anything can be "what's new" if the user has never come across it.<p>Personal curation of content can be one of the most satisfying activities of my day yet, it's the most gimped with services.
