Ghost of Love
"One" is not a song that was meant to be belted out. There's no belting out in the studio version, and live, the only time there's any belting out is in the 'knockin' at your door' coda. It is a song that is best served by vocal subtlety and the ability to express emotion with voice without going into vocal acrobatics and screaming. It is supposed to be a soundscape-y alternative pop/rock ballad, not the kind of over-the-top power ballad MJB tried to make it.
How the hell would you know how it is 'meant' to be sung or what type of song it's 'supposed' to be? Is it completely lost on you that the makers of the song did it in this manner with her many times over? And let her release it on her album? You don't own the song, no fans do. U2 does, and they did what they wanted with it. The only person who has the right to dictate how a song is 'meant' to be done is the writer.
