Why gospel why?

My buddy Tony gave me a copy of the music from the film Across the Universe. I have not seen it, but I believe it's a trippy (in the best possible way) piece using Beatles music. I am sitting in the library and Let it Be comes on over my ear buds and I start crying. Yes, the sound is heartfelt and all, but the water doesn't start until the gospel choir lets loose.

I tend to get teary at all things gospel.

Why is that?
