According to Billboard, the change was retroactively made to acknowledge an interpolation of the group's 2007 mega popular single, "Misery Business." Although it's unclear when exactly Williams and Farro were credited, the pop rock singer reacted to the news with an Aug. 25 post on her Instagram Story.
Williams reposted an image from Paramore's publishers, Warner Chappell Music, which she captioned, "Our publisher is wildin' rn [right now]." The organization's original post gave a "huge shoutout" to Williams and Farro for being named songwriters of "Good 4 U." Reps for Rodrigo did not immediately respond to E! News' request for comment.
Meanwhile, a source confirmed to Billboard that Rodrigo and Paramore's respective teams were in communication prior to the song's release in May. Since then, the third single on Rodrigo's history-making debut album, Sour, "Good 4 U" has peaked within the top 10 music charts in more than 15 countries.
In July, Taylor Swift, along with vocalists Jack Antonoff and St. Vincent, were also reportedly added retroactively as co-writers for Rodrigo's hit, "Deja Vu." Those credits acknowledge an interpolation of the singer's 2019 song, "Cruel Summer."
Fans of both Paramore and Rodrigo drew comparisons between the tracks after "Good 4 U" hit airwaves earlier this year. Ironically, in 2018, the group actually announced they would be retiring from performing "Misery Business" from their live shows, with Williams noting that she no longer connected to the lyrics she wrote during her younger years. Now, with Williams and Farro's newly added songwriting credits, their misery business has officially taken on another life of its own.
