Chills every time

Non-Muslim here, I wanted to ask about the evening prayer recited/sung from mosques (the one played over loudspeakers).

You know how old vinyl records have that slight static/crackle that somehow makes music feel fuller and more complete? I get a similar feeling from these old-school speakers (at least here in South India), but I don’t think it’s just that.

There’s definitely something about the words/sound itself that really stands out. No matter what I’m doing, whenever I hear it, it gives me goosebumps without fail.

I’d love to understand more about it what exactly am I hearing? Is it the melody, the recitation style, or something else? And who is typically behind the recitation?
