“Brown Earth Rumble” is perfect for sleep, and the ability to layer sounds is *chef kiss*

This sound is perfect for sleep. I have lifetime memberships to 3 apps that cost me close to $500 all together. This has been my go to sound and app for two months… I strongly recommend this app. Nothing comes close. It makes me sleep like a baby! THANK YOU!
