NASHVILLE, Tenn. (WKRN) – Justin Bieber and Skrillex are facing a lawsuit for copyright infringement for the multi-platinum song “Sorry.”

Casey Dienel, who performs under the name White Hinterland, filed the suit Wednesday in federal court in Nashville against the two artists.

It was also filed against the song’s writers, producers, publishers, record labels, and distributors, some of which are based in Nashville.

Dienel alleges “Sorry” uses a vocal riff from her original recording “Ring the Bell,” which she says she spent four years creating before its release in 2014.

The suit claims the defendants “literally sampled” the song, noting since it was released first they had “access to ‘Ring the Bell’ prior to the creation of ‘Sorry,’” which was released in 2015.

According to the lawsuit, “the vocal riff is a qualitatively and quantitatively distinct and integral element” of her song and the defendants “knowingly and unlawfully copied the original, protectable elements of the musical composition of ‘Ring the Bell.’”

The vocal riff can be heard multiple times throughout both songs beginning in the first few seconds of each.
