In retrospect, I should not have made a value judgment on the quality of the singing. It was not important. The main point was is it singing? My own view was at the time and remains, that it is singing. There is melody, rhythm and harmony there - all the three main elements of music.

As leeneia says, it is a typical modern gospel music influenced Christian song.

I have had this argument with my wife several times before and it never gets resolved - and probably never will. She simply does not think that the modern gospel style songs have a singable melody. The fact that there are several hundred people singing along does not seem to convince her and argues that this style of loud, enthusiastic singing constitutes shouting. My daughter tended to agree with her describing the singing as chanting. Well surely chanting is a form of singing?

I wanted to test my thoughts out in a forum comprised of people who were interested/involved in music to see what the reaction is.

Interestingly, separating the sound from its associated video made the melodic aspect stand out more clearly for me. I was not distracted by all the people's actions on the film.
