O'Connor passed away yesterday aged 56, with a cause of death yet to be confirmed. Releasing her first of 10 solo albums in 1987 with 'The Lion And The Cobra', the singer was well and truly put on the worldwide map with her beautiful cover of 'Nothing Compares 2 U', written by Prince.
The song propelled O'Connor to international stardom, winning numerous Grammy Awards, along with being named Artist of the Year by Rolling Stone Magazine in 1991.
Following tributes from the likes of Taoiseach Leo Varadkar, President Michael D Higgins, along with artists like Bryan Adams and more, tributes continue to be paid to the late singer, including being hailed as "the greatest voice of her generation" by writer Caitlin Moran.
Victoria Mary Clarke the wife of Pogues legend Shane MacGowan thanked Sinead O'Connor for her "love and friendship".
"We don't really have words for this but we want to thank you Sinéad", she wrote. "For your love and your friendship and your compassion and your humour and your incredible music".
"We pray that you are at peace now with your beautiful boy. Love Victoria and Shane".
In a second post, Victoria Mary Clarke also added, "She told outrageous jokes at the most inappropriate times and she cracked me up! There will never be anyone even remotely like her".
Singer Mary Black recalled her 2017 performance of Adeste Fideles on the Late Late Show with Sinead, calling it a "special moment".
"She sang with such truth. Every word she sang in any song, you felt she meant it from the bottom of her heart", Black said. "She had that sort of brilliant, raw talent that came out no matter what song she sang".
"It was in old ballads ... or it could be a hymn. She never just sang, she gave it her whole soul and heart. And I think that's what made it so special", she added, "She was fragile and fearful, but fearless as well, in that when she felt something was wrong or when she felt she needed to speak, she would speak".
"And that was an unusual trait in a woman, particularly going back 20 years when she was starting out".
Dublin band Aslan who collaborated with Sinead O'Connor for 'Up In Arms' in 2001, also paid homage to the singer. The band's singer Christ Dignam died last month.
Oscar winning actor Russell Crowe recalled meeting Sinead O'Connor in Ireland when he was working, calling her "an amazing woman".
"In a conversation without fences we roamed through the recent Dublin heatwave, local politics, American politics, the ongoing fight for indigenous recognition in many places, but particularly in Australia, her warm memory of New Zealand, faith, music, movies and her brother the writer", he said.
"I had the opportunity to tell her she was a hero of mine", the actor added. "What an amazing woman. Peace be with your courageous heart Sinéad".
Other household names to pay tribute to Sinead O'Connor include Big Bang Theory star Mayim Bailk, Margo Price, Belinda Carlile, Tom Morello, UB40 and more.
Sinead's family and friends are devastated at her passing, and have requested privacy at this difficult time.
