This song by the very talented Sarah Hart and Kevin B Hipp is a reboot of the Magnificat I suppose. There are three verses with different tunes over the same chord progression, a bridge and a coda. The tune has very fiddly syncopations and is for all these reasons a solo vehicle with maybe a singalong chorus. Now since the song sings in the voice of Mary I wonder if it is even appropriate as a solo song. The tune itself really only gets interesting in the coda. The original can be heard here with the harmony vocals prominent in the refrain.

This fair attempt does show how difficult the song is. It also sounds like they are using a click track that everyone is ignoring.
