Nice pretty little song, well performed. See? just cos it is about a fairy on a cloud does not make the music bad.
I like many hymns and am in awe of European religious buildings; and people say: 'you are supposed to hate that stuff cos you are an atheist'. Those songs and those buildings were created by people, people with a particuar talent, that they were muslim or christian or whatever has and had nothing to do with the execution although it might have something to do with the motivation.
My college professor for Romanticism was a huge fan of Thomas Hardy, and I believe wrote his dissertation on him (so naturally I picked up a little history). Hardy loved attending service with his wife, and admired Catholic and Anglican architecture, but he was an atheist.
