I love the tiny pitter-pattering sounds that make everything seem so huge, so endless. Listening to those sounds, trying to find them while walking along a misty path is magical.
Rain makes puddles, puddles make reflections (and illusions of parallel universes), and reflections make good photographs.
I love the wet, too. It's just refreshing and easier to think. Rainy days ar perfect for music.
Rain makes me smile, when I'm walking home after a bad day. It starts puring, puring endlessly... And the sky is always beautiful and dark; if there's sun, the rain glitters against it. aaaaah.....!

I love music that has snipets of recorded rain in it.
