Jason Isbell: "You can't aim art." New or a quote?

On The New Yorker Radio Hour, songwriter and performer Jason Isbell shared a story - he’s a charming and witty man - about how when he’s singing a line in a song of his about giving up booze, the audience typically chimes in, sloshing their beers and hooting. The interviewer asked him, as a guy who had real issues with alcohol and is thankful for his recovery, how he wraps his brain around it. He says something about being pleased that he has an audience and respects the irony and humor. He responds to a clarifying question with a wry “You can’t aim art, man.”

That’s such a nice little aphorism that I assumed it was a quote. I have googled it and get nothing. Was it really just a toss-off line? If so, jeez, that’s good.

He ain’t no Mike Cooley.
