Kudos for making a fresh attempt to solve the music discovery problem, which is often a source of frustration for me, but the italicised words above made me lose interest. I have never had music in my inbox and I never want to have music in my inbox. For me, instead of being "effortless", that sounds like loads of effort.
(I'd consider paying for a subscription to a one-click solution that imports curated playlists directly into iTunes or Spotify.)
It's free, but you can donate to keep it going.
Love the feedback.
