Monkees’ song ‘changed everything’

In his Sunday column, Doug Clark writes of the Monkees’ song that “changed everything”:

Today Clarksville examines “Last Train to Clarksville,” the pop song that changed everything. It came blasting over the AM radio waves a half-century ago this year, topping the charts and propelling four actors with marginal musical skills to the status of rock superstars. The Monkees.

The unbridled success of this made-for-TV boy band arguably set off a chain reaction of societal disasters, including … Escalation of the Vietnam War, the election of Richard Nixon and Watergate, disco, New Coke, Milli Vanilli, Roseanne Barr singing the national anthem, the O.J. Simpson trial, the invasion of Iraq, Donald Trump’s run for the White House and The Spokesman-Review’s irregular Clarksville feature that you are enjoying here today. So what made a simple 1966 song about rail travel and the importance of wearing a timepiece powerful enough to provoke such a cultural tailspin? More here.

Question: Is there a song that “changed everything” for you?
