Calculating Music Similarity With Mobile Device Playlists, Jacob O'Bryant, Dennis Ng

Journal of Undergraduate Research

Music recommendation systems, such as Pandora and Spotify, help listeners to discover new music. The similarity of different songs is an important measure used in music recommendation. We have studied manually-created playlists on mobile devices to see if they can be used to accurately calculate song similarity. We collected playlists from 41 research subjects and used a co-occurrence model to calculate similarity between songs in the collection.
