美国国家公共电台 NPR Katy Perry, Juicy J And Dr. Luke Liable For Copyright Infringement For 'Dark Horse'

（单词翻译）

DAVID GREENE, HOST:

Good morning. I'm David Greene.

(SOUNDBITE OF SONG, "DARK HORSE")

KATY PERRY: (Singing) Mark my words, this love will make you levitate¹.

GREENE: This really takes you back to the summer of 2014, doesn't it? Well, a jury here in LA found that Katy Perry's "Dark Horse" copied this song.

(SOUNDBITE OF SONG, "JOYFUL² NOISE")

FLAME: (Singing) Your boy's been a Christian³ - how long? - quite a few years. Yes.

GREENE: That is "Joyful Noise" by the Christian rapper Flame. Perry and her co-defendants say they had never heard of it, but the unanimous verdict said it was a perfect storm of copyright infringement⁴.
