Müdz by Spotify

Müdz, (pronounced "moods"), is an app by Spotify that creates playlists for you specifically. The app takes several things into consideration when curating these playlists: Current location, weather/season, time of day, schedule (through your calendar), recent searches and likes, route, and most importantly: your mood. The app will even ask you how you are feeling that day to really get a sense of what music you want to listen to for the time being.
