Recommendations for Relaxation/Fall asleep music ?

Erik Satie. His music will take you to a peaceful place. 

I particularly like Alessandra Cilletti "Esoterik Satie" but there are several good ones. 

There also many "Sleep Music" playlists on streaming services. 

Long Division - Low

Low +2

I'll second the Chopin, and Music for Airports. Try to find MfA by a group called Bang on a Can. Unlike Eno, no synths, but live musicians. 

I'm generally not a fan of Andreas Vollenweider, but his Caverna Magica is suitable for casual or serious listening, plus it has great sonics.

Brian Eno Music For Films

Allman Brothers In Memory of Elizabeth Reed 

Stormy Monday

Kind of Blue
