It's been hammered home just how Irish this movie is, but that doesn't mean that Martin McDonagh wanted to go overboard with it. The critically-acclaimed writer and director apparently drew the line at the film's soundtrack as the point where things needed to be a little less Irish. According to the film's composer, Carter Burwell, he was explicitly told why traditional Irish music wasn't going to work for "The Banshees of Inisherin," despite the overwhelmingly Irish setting, cast, and story.
During an interview with Variety, he said that McDonagh told him, "I hate that deedle-dee, old world Irish film music" and instead demanded something more contemporary that would fit the characters on screen. In another piece by The Wrap, he added more context by saying, "It clearly touched a nerve of some sort, so I never brought that up again. But it wasn't obvious what else it should be, so I waited until I saw some of the footage before I even started thinking about it again."
