Love the sound of water in any form. Rain, waterfalls, fountains, etc.
Snow?
I can't say I've ever heard much snow....generally the sound of spinning tires and cussing drivers.
Water, on the other hand, is like therapy. Rain, waterfalls, streams, etc are nice, but the ocean is best. Even angry, stormy ocean sounds are like a drug. If it is angry and stormy, I want to be in a robust building, but I've been through some big storms in my life and even those are fascinating. My favorite ocean sound is either early in the morning or late in the day, into the night.
