I was shocked over the amount of tranquility music we sold. Tranquility was nature sounds. I didn't know about white noise back then, but we probally had it. It was basically music produced cheaply that supposedly relazed people.
I got it. People are stressed. Did listening to calming nature sounds help me--no, but listening to AM radio on a boring station does calm me down, or keeps negative thoughts away.
My sleepy time music was Classic music. Pretty much everything.
Even then becoming a musician was as hard as becomming an artist. There was just no formula besides 1 in a million talent, like Elvis, or just sheer luck, and that meant exposure.
(I am thinking about leaving an old iphone strapped to a tree to record creek sounds tomorrow, and plop it on Spotify under "Songs to calm. Natural, and organic music."), or never leave my house and produce it digitally?)
