"The user can use thumbs up and thumbs down buttons to declare whether they like a track or not, which determines whether similar songs should be played in the station.[40] A second thumbs down to the same artist will ban that artist from the selected station.[41] A thumbs down immediately skips a song, but the number of times a user can skip tracks is limited unless they are using one of the paid subscription plans, or opts to watch a video ad.[42][43] More than 450 musical attributes are considered when selecting the next song.[44] These 450 attributes are combined into larger groups called focus traits, of which there are 2,000.[45] Examples of these are rhythm syncopation, key tonality, and vocal harmonies.[45]"
