In the world of entertainment, the line between “inspired by” and “stolen from” is expansive yet blurry. It seems Ed Sheeran has gotten into trouble with the copyright of his song “Photograph”.

The songwriters behind X-Factor winner Matt Cardle’s song “Amazing” alleged that Ed Sheeran has copied “Photograph”. The songwriters are asking for $20 million as compensation.

Interestingly, Richard Busch is representing the songwriters as their attorney. Earlier, the “Blurred Lines” case was won by Martin Gaye’s family, who was represented by the same attorney.

Gaye’s family sued Robin Thicke and Pharrell Williams over “Blurred Lines”. They won $5.3 million as compensation.

Matt Cardle’s song “ Amazing” was written by Martin Harrington and Thomas Leonard of HaloSongs, and the songwriters have filed charges of statutory damages and a permanent injunction, which means preventing the reproduction, sales, public performances, distribution or other use or exploitation of “Photograph” apart from the $20 million compensation.

The lawsuit also stated that both songs share almost the very essence of the work.

“The similarities go beyond substantial, which is itself sufficient to establish copyright infringement and are in fact striking. The similarity of words, vocal style, vocal melody, melody and rhythm are clear indicators, among other things, that “Photograph” copies “Amazing”,” says the lawsuit.

Vanity Fair notes that to prove it, plaintiff claims evidence as “The chorus sections of “Amazing” and the infringing “Photograph” share 39 identical notes—meaning the notes are identical in pitch, rhythmic duration and placement in the measure.”

The lawsuit also states that almost 90 percent of the chorus on “Photograph” are similar to or at least mimic the chorus in “Amazing”. It also says that the chorus is a big part of the song, almost 70 percent in “Photograph’s” case.
