In a bold move to protect the sanctity of state-specific melodies, the U.S. Aural Trade Authority (UATA) announced today a 50% duty on Canadian hummed refrains crossing the Detroit-Windsor border. Under the new policy, agents stationed at the humming checkpoints will now demand triplicate voice samples and state-of-origin affidavits from all travelers, transforming a casual cross-border commute into a cacophonous bureaucratic ordeal.
Reports from the UATA indicate that this humming audit is expected to yield a staggering 17% increase in Midwest song variants, as Canadian harmonies are held for mandatory three-day duty appraisals. "We are conserving the unique cadence of our local soundscapes, particularly in preserving the pure Illinois drawl of three previously at-risk county-fair standards," stated agency director Marla Lipley at this morning's press briefing.
Local musicians are already adapting. "I guess we'll have to train our ears to spot Canadian tunes before they even arrive!" lamented Bert McGuffin, a local humming enthusiast and organizer of the annual Humming Jam Festival. Creatively adapting, Bert plans to offer 'Quick-Fix Humming Workshops' to help compatriots master the art of improvisational mutation, stating that "the only way to protect our songs from becoming a Canadian hit is to make them our own first!"
Critics of the new regulation argue that the humming audit is a fine example of escalating bureaucratic absurdity, where the enforcement of musical integrity breeds more chaotic variation than it suppresses. As the melodies of Canada whistle through the air and into the ears of unsuspecting citizens, the more the UATA tries to control the song, the more wildly it will mutate.
