I really hate Pandora. The last thing I want is to hear the same music over and over. What would it take to make an anti-Pandora that would non-randomly create playlists that specifically vary the features to avoid similar recordings and maximize diversity and broad scope of music?
This sounds like something for #acousticbrainz. ListenBrainz doesn’t know anything about audio features (other than if they’re included in the submitted listen (meta)data). Moving there.
