Because of the nature of the movie plot, only a small portion of the movie's "show" is ever heard including the repetitive playing of "I've Got You Babe" and two goofy morning deejays warning, "It's cold out there today!".
Masters of None is a podcast described as "former radio guys Mike, Art & Jay, who debate and answer mankind's most important questions each week." This week, they have used what little of the Groundhog Day movie radio show the world knew of to create a 30 minute version of what they think it might have sounded like - had you had to opportunity to hear more of it.
I found the concept clever and amusing.
