Birthday Song (2 Chainz song) was banned by Sonny Digital.
In a 1998 episode of the television show Sports Night, "Intellectual Property", character Dan Rydell sings the song to his co-anchor during a telecast, forcing his network to pay royalties, and causing him to ask his colleagues to choose public-domain songs for him to sing for their birthdays
 In 1988, Warner/Chappell Music purchased the company owning the copyright for US$25 million, with the value of "Happy Birthday" estimated at US$5 million
