I’d like to add more information regarding the background music to choose from. There is a clear distinction between those two: One is brighter and the other is darker. Here’s how I like to make the decision:
As a visitor, I’d actually lock my eyes on the ceiling and the wall details after initially seeing the lights from the window. The atmospheric composition(as in art, not in music composition) is structured, dark and somewhat dense from the “fog”. We recognize that we are in a cathedral and it’s an indoor area.
With this in mind, the first track does not align well with the indoors and their decors. It is adequate enough for the shining lights from outside, but that takes too much focus away from the actual work of this place. So therefore, the second track would be chosen for its overall darker tones. You should also make good use of the ambience reverb by using SoundService.
