Calum Scott's single 'Dancing On My Own' has had almost 327 million streams on Spotify, but it was his cover of the song that had the internet going crazy three years ago.
The 30-year-old got his big break on Britain's Got Talent in 2015, earning a standing ovation from the judges - and the elusive Golden Buzzer, which sent him straight through to the next round.

Since then the single's gone two times platinum in New Zealand, and he's had several other huge hits including 'You Are The Reason'.
But behind his success, Scott struggled with his sexuality and this month he released an emotional video sharing his coming out story.
"It was a really personal story that really made me suppress who I was for many years after," he told Newshub.
Scott says the most painful part about coming out, was when his friends abandoned him after they learned he was gay.
Now he's written about that experience - and the huge support he's had from his mother - in his most personal single yet.
"It was a song that I always had to write, and a song I never thought I'd be able to share," he said.
"This song has so much bones behind it and has such a wider discussion, not only about sexuality but about acceptance."
'No Matter What' was meant to be part of his debut album, but Scott didn't feel ready to share it with the world until recently. Now he hopes his own story will help others.
"This hopefully will be a movement. I want to help people, I want to inspire people, I want to make people more compassionate."
Scott played the single for the first time in Auckland on Tuesday, at his first ever New Zealand show at the Powerstation.
