Playlist Brew is a playlist organization, customization, and generation tool for Spotify that is centered on the idea that experiencing music is entirely subjective. Automatic playlist generators or canned mood playlists may not exactly fit the vibe you want, or might contain songs you don't know or don't like. But manually curating playlists from your own music is a slow and static process; your music tastes change over time and those old playlists you spent so much time perfecting become stale and unused. Playlist Brew provides an easy-to-use interface for labeling and categorizing music according to one's own tastes, then automates the tedious playlist creation and organization process seamlessly. Create and categorize all of your music by any measure you deem fit, then generate a playlist for any mood or setting with all of the music you love, all at the click of a button. Watch as your old playlists continuously update in the background with newer music, keeping them fresh with the vibe you designed them with. Have a new playlist idea? Instantly bring it to life using your own custom content curation and criteria-based generation.
