Anthem is an iOS application that allows users to curate entire playlists with just one song in mind. By selecting a single song—your anthem—your playlist is already on its way. Other users will contribute songs they think fit your song and mood, which will be set by mood tags. This encourages less time spent scrolling through songs to create your own playlists, but also the social sharing of music. To avoid internet trolls, a voting system is in place. After a certain amount of negative votes, a song will be removed automatically from the user's playlist to ensure that songs follow the song and mood set.
