Every track on Play was licensed to various films, advertisements, and television shows, as well as independent films and non-profit groups.[60] The move was criticised and led to some to consider that Moby had become a sellout, but he later maintained that the licenses were granted mostly to independent films and non-profit projects, and agreed to them due to the difficulty of getting his music heard on the radio and television in the past.[14] In 2007, The Washington Post published an article about a mathematical equation dubbed the "Moby quotient" that determined to what degree had a musical artist sold out. It was named in reference to his decision to license music from Play.[14][61]
