All good yet very different versions.
I went with the Voices of Angels version. I liked the Hayley and Meav arrangements better than some parts of the CW arrangement, but Eabha's haunting voice and the climactic harmony made that version unique.
I'm possibly a little biased having heard the VoA version live 3 times (2x at VoA and once on the 2016 HfC tour) and Tara smiled at me during the song at the HfC concert and so did MC so ... sorry game over.
