No popular music genre despises the present as much as country music. Through quirks of form and function, all other radio-ready music is incredibly focused on its immediate surroundings. Pop has trendiness in its very bones, and its songwriters’ striving for universality tends to create songs focused on broad, current feelings: the sharp sting of a fresh heartbreak, the effervescence of new heartbreak, the joy of dancing in this club right now.
