Music recommendations

Recent work is focusing on recommending music and playlists. Using data and APIs available from Spotify, severval master students are working on topics such as personalized mood playlists and peak-end rule effects in the overall evaluation of playlists. At JADS we are working on a spotify-based group recommender system that will construct optimal playlists for groups of users in a bar or that share on office.
