The Los Angeles Times reported that in 2017, members of 3LW sued Taylor Swift claiming she lifted parts of the “Playas Gon’ Play” chorus for her song “Shake It Off.” In “Playas Gon’ Play,” the hook “Playas, they gonna play / and haters, they gonna hate” is repeated. Taylor’s “Shake It Off” repeats “Cause the players gonna play, play, play, play, play / And the haters gonna hate, hate, hate, hate, hate.”

It’s not so much the actual words but rather the familiar order they are both organized in. Players gonna play and haters gonna hate.
