How Many Rain Songs Are There?

Mother Nature is packing quite a punch today with heavy rain falling throughout the area. Streets and highways are taking on some heavy amounts of rain water today so drive carefully. It got me to thinking about songs about rain.  Songs like "I Wish it Would Rain", "Rainy Days and Mondays" and so forth. There are a ton of them that have been recorded over the years.  So lets see how many songs we can come up with. Let us know of your list!
