This sexual romp is a bouncy marching song full of horns, looped samples, cossack-like music and call-and-response vocals. It finds Gaga singing of a S&M desire for being tied up and bitten. The tune was produced by Teddy Riley, who was an architect of the late 1980s and early '90s New Jack Swing sound and was responsible for hits by Bobby Brown, Guy, and Keith Sweat. He went on to work with many leading names in the music industry including Boyz II Men, Snoop Dogg and the late Michael Jackson.
Riley's daughter Taja Riley was credited with co-writing the song. However, her father sued her in 2013 for copyright infringement and fraud claiming that she didn't co-pen the tune. The New Jack Swing pioneer said that she lied about the songwriting credit and should not have received a publishing deal from EMI Music.
Teddy Riley also filed suit against Lady Gaga later in the same year, claiming he was promised 25% of writing fees, but has received nothing.
"Piano Man" was inspired by Billy Joel's time playing at a piano bar in Los Angeles. The "real estate novelist" was a guy who always talked about writing a book, but spent all his spare time in the bar.
