Hozier told RTÉ Entertainment that when it comes to activism and speaking up for what he believes in and supports, he has the view that "solidarity costs you nothing" and that "life is too important to not help out where you can."

Hozier, real name Andrew Hozier-Byrne, is known for speaking out on issues that he supports, marching for causes he believes in and boosting up others doing the same, and his efforts are something he sees as a very small contribution to those who are "in the trenches."

"The way I see it, life’s too short and life is too important as well, and the lives of other people are too important to not help out where you can, and for me it’s not like I’m in the trenches, I literally make noises for a living," Hozier told RTÉ Entertainment.

"On some of the stuff I maybe will give a signal boost to or go to a rally or march or sing a song or whatever, I'm not in the trenches, I'm not living that in the same way people who really dedicate their lives to it are, but I still think it’s a very small thing to contribute and that solidarity really costs you nothing."

The Wicklow man isn't afraid of upsetting people who may have differing views to him, or who have the view that musicians have no place to get involved in political or world matters outside their industry.

"If it does piss off somebody, sometimes, I don’t want to be a cynic about it but you know, if you’re pissing off the right people it's not a bad thing. If it’s a case of you're pissing off people, sometimes it’s good to piss off the right people.

"I don’t think there’s anything remarkable about the servile worship of powerful institutions. It’s nice to speak up for people who otherwise wouldn’t have a voice."

He added, "At the end of the day though, I'm still just a noisemaker, I'm just a musician. There are a lot of things I have great admiration for and if I can do anything, sometimes I try."
