साल्सा GORRRDAAAAA!!!! If आप want to shake away the sadness of a rainy day, put some साल्सा and dance until आप can't dance anymore and you'll see आप won't notice when it stopped raining!!!
A good song for a rainy दिन well for me that's "Rainy Days and Mondays" द्वारा 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!
