 In March 2015, band founder Jack Stratton proposed a more equitable model for Spotify payout distribution in which each artist's payout is based solely on that artist's listeners, rather than every listener using the service.Vulfpeck released "Sleepify" in March 2014 as a means to fund a concert tour of the same name; all of the shows were to be free of charge, but funded solely using royalty payments from the album on the music streaming service Spotify.The service calculates royalties based on how many times a track has been played, counting a single play as listening to the song for at least 30 seconds.
