LOS ANGELES: The 22-year-old Canadian pop star and song writer Justin Bieber along with his co-producer Skrillex of the smash hit track ‘Sorry’ are being sued for swiping a vocal riff in the song from another artist who claimed that it was featured in her song a year before ‘Sorry’ was released. Casey Dienel made a public statement on Thursday. She is an indie artist and she performs with her artist name ‘White Hinterland’. She sued Justin and Skrillex for stealing her copyrights from her song ‘Ring the bell’. The defendants include producer Skrillex and Vivendi’s Universal Music Group. U.S. District court in Nashville filed the lawsuit. No public comment has been made by the spokespersons of both Justin and Skrillex about this news. The track “Sorry,” which shows up on Justin’s album cover of “Purpose” has more than 1.42 billion YouTube views, assumed that “specific and unique characteristics of the female vocal riff” from her song, sampling it for the first eight seconds of “Sorry” and several times afterwards. She said even The New York Times Magazine noted the riff’s individuality, when it praised Bieber’s song for its “cooing arpeggio that feels like a gentle breeze on your brain” in a March 13 article titled “25 Songs That Tell Us Where Music Is Going.” Bieber’s song ranked No. 1. Dienel also said she reached out to Bieber to discuss a resolution, but he “ignored” her claims and refused to talk. The lawsuit seeks unspecified damages, including from profits generated by “Sorry.” Dienel’s “Ring the Bell” appeared on White Hinterland’s album “Baby.” It is common for well-known singers to be accused of stealing song ideas from other composers. Kanye West was sued last week for allegedly taking part of his 2013 song “New Slaves” from a 1969 song by a Hungarian rock singer. Led Zeppelin’s Robert Plant and Jimmy Page face a June 14 trial over whether they stole opening chords for their 1971 song “Stairway to Heaven” from a 1967 instrumental. The Bieber case is Dienel v. Warner-Tamerlane Publishing Corp et al, U.S. District Court, Middle District of Tennessee, No. 16-00978.
