Kacey Musgraves was back at The Tonight Show Starring Jimmy Fallon last night (Feb. 26), where we got the television debut of "Space Cowboy" off the East Texas native's upcoming new album, Golden Hour.

Three days ago she shared the inspiration for the new song with fans on Instagram

"One day I was out at the barn watching this stallion charging powerfully from one end of the arena to the other, bucking and galloping at full speed all alone. Though I was 'safe' on the other side of the arena wall, it kinda scared me when he came flying toward me..barely stopping in time. My riding teacher saw him coming at me and yelled at me to move away," she writes.

"I said 'I’m fine! The gate is closed!' to which she said, 'Girl - when they wanna go they will go...there ain’t no point in even shuttin’ the gate.' It really made a mark on me when she said that and I wrote it down. SPACE COWBOY came a couple days after with @shanemcanally + @lukerobert. Make peace with what doesn’t belong. You’ll find something better."

Golden Hour is set for release on March 30. Musgraves is currently on the road with Little Big Town and Midland on the Breakers Tour.
