Apparently mood music apps are a thing now. Last week I discovered Rockola, a streaming music app that finds music based on mood from various time periods. Today I came across Moodagent, an app that also creates playlists based on mood. The difference is that Moodagent playlists are generated from songs already in your music library.
The first time you run Moodagent, it will sync your music collection with an online database filled with millions of tracks. Each song has a profile so that Moodagent can decide which songs are tender, sensual, angry, happy, and so forth. The app downloads profiles for each song in your collection so that you can generate playlists more quickly and without an internet connection.
