Hozier is suing Chilly Gonzales.
The 25-year-old singer/songwriter has started legal action against the musician after the latter accused him of plagiarism with his hit single 'Take Me To Church'.
Chilly, 43, recently commented on the similarities between the multi million-selling song and a track by his former collaborator Feist titled 'How Come You Never Go There'.
However, Hozier's manager Caroline Downey has hit back at the allegations which she has slammed as being "groundless" and told the Irish edition of The Sunday Times newspaper that Hozier intends to pursue legal action.
In a clip posted on YouTube by Chilly, which has since been deleted, he described the track as "the exact same thing" as Feist's 2011 track.
He said: "This sounds quite familiar to me, I must say.
"This very slow and noble triple time and those sad chords. I think I know what it might be.
"It's almost the exact same thing. That's a crazy coincidence that my good friend and musical little sister Feist with her song 'How Come You Never Go There' had the exact same idea to use those chords and that slow triple time as Hozier. What are the chances?
"I'm being told by the research staff that Feist's track came out well over a year before Hozier's. Doesn't look so good does it? 'Take Me To Church'? Maybe Feist should take him to court."
