Very cool! I think it would be nice if eventually it could get access to your spotify data somehow and improve results by knowing what you like to listen to/listen most to.
@arco1991 - thank you for your response and feedback. I agree it would be cool to understand the user's Spotify tastes and tailor the playlist according to that. However, I consider that use case as Personalization use case versus Recommendations. For now, I am focused to get the recommendations right based on the description of the playlist.
