You might have heard the original version from Kate Bush, it was a hit in the UK and a minor hit in the US. The song is about someone wanting to switch places with their partner, kind of a take on "deal with the devil". Basically, you want to help this person get through whatever they are going through so you would switch places so it doesn't take a toll on them. The song was originally going to just titled A Deal With God but the record label felt that the song wouldn't do so well in religious countries because the word God was in the title. Here is Kate Bush talking about the song.
"I was trying to say that, really, a man and a woman, can't understand each other because we are a man and a woman. And if we could actually swap each other's roles, if we could actually be in each other's place for a while, I think we'd both be very surprised! [Laughs] And I think it would lead to a greater understanding. And really the only way I could think it could be done was either... you know, I thought a deal with the devil, you know. And I thought, 'well, no, why not a deal with God!' You know, because in a way it's so much more powerful the whole idea of asking God to make a deal with you."
Here is the original version by Kate Bush:
There have been a ton of other covers of this song and we should just leave it alone. The song loses it's beauty and magic if it's covered soo much. These covers are decent. Faith and The Muse were the only ones I felt who were real fans of the original and who did the song justice. It's rare that a cover can be as good as the original.
