William Hung was offered a $25,000 advance on a record deal from Koch Entertainment in 2004, and released three albums on that label in 2004 and 2005. The albums mainly consisted of covers of pop and rock songs, including "She Bangs".

Hung has appeared in commercials for the search engine Ask.com, the Game Show Network (spoofing Freddy Mercury and singing an off-key "We Are the Champions"), as well as the mobile phone service provider Cingular Wireless.[citation needed] He also appeared to sing "Take Me Out to the Ballgame" in May 2004 at the Rogers Centre for the Toronto Blue Jays.[4]
