Moodwill.

Moodwill is a free web app made by a nature lover. It provides high quality sounds of the nature online without requiring any download. Moreover, you can listen to any music you'd love to hear on top of the nature sounds for a better experience.

Created by a young insomniac named Fath, Moodwill also known as Pluvioniverse, started as a project in 2011 and was originally under the name MyRainy Piano. As any insomniac knows, sleeplessness can affect your health in many ways: less concentration, memory issues, fatigue... and doctors suggestions aren't always that perfect, that's why this young insomniac decided to create a simple but effective solution to the problem.
