There are a million way I'd like improve Spotify (mostly implementing better management of the music I already like rather than funneling me towards new music) but I also remember a time not too long ago when hearing a new album was much more expensive and difficult. I used to pay $17 a pop for new CDs regularly, and as a kid in the 90s, that was real money! We might argue that the current equilibrium is unsustainable for and unfair to artists, but for consumers, Spotify/priced streaming is a huge advancement.
