Thanks for the Sea and Cake link. I love their music so much and I often forget to listen to it. It's incredibly soothing. Oui is one of my favorites. I no longer listen to music when I'm falling asleep. No matter how soothing the music, it's too stimulating. It makes me think to much to sleep. But when I was a kid I used to listen to Sun King by the Beatles on loop. The crickets, the guitar, the choral-vocals all made me chill in a great way. Plus for many of the lyrics I have no idea what they're singing which doesn't make me "think" as much as lyrics in english. Love the bass.
Sea and Cake is great both for daylight listing and some of their more instrumental stuff at night. I find one of the great things about the fan like captainduncan mentioned is that its just enough to break up the silence but repetitive enough to not simulate your mind to much.
