сальса GORRRDAAAAA!!!! If Ты want to shake away the sadness of a rainy day, put some сальса and dance until Ты can't dance anymore and you'll see Ты won't notice when it stopped raining!!!
A good song for a rainy день well for me that's "Rainy Days and Mondays" by The Carpenters..as for genre I particularly don't mind what I listen to anytime but if I had point one out it would have to be Easy Listening!
