I like this song for its blending of the voices. Once I was singing lead to Holy Night, I hadn't rehearsed when during performance two ladies came on stage joining in the chorus with the most amazing harmonies I have ever heard...it was spiritual sound....it was the highest compliment I have been given...it was the best Christmas present of all. I love singing worship songs when I hear they have uplifted someone as well. Thank-you Siwon for both uplifting me up and calming my spirit with song, both this song and Harmony.
