Lifehacker: Get Free Ambient Work Music With Flow State . “Every morning Flow State emails subscribers a set of background music, mostly wordless, to soundtrack your work day. And they’re pretty good at digging up non-obvious music, some of which isn’t even available on major streaming services (though almost all of it is on YouTube). Past artists include Max Richter, Olivier Messiaen, Debussy, Johann Johannsson, Tangerine Dream, Kaoru Inoue, Brian Eno, and William Basinski. (Yep, almost all men, sorry.) Occasionally there’s a DJ mix that incorporates several artists.” Flow State used to cost money but now it is free.
