Sean Hall and Nathan Butler told a Los Angeles federal judge they will dismiss their 2017 case with prejudice, which means it cannot be refiled.
In "Shake It Off," Swift sings: "the players gonna play, play, play, play, play, and the haters gonna hate, hate, hate, hate, hate."
"Playas Gon' Play," written by Hall and Butler, included the phrases "playas, they gonna play, and haters, they gonna hate."
Swift told the court in August that she had never heard 3LW's song before writing "Shake It Off."
She said she had heard the phrases "players gonna play" and "haters gonna hate" used commonly to "express the idea that one can or should shrug off negativity."
