Though it came out in July of 2006, The Ballet's "I Hate The War" stands as the song of 2015.
Nine years after the song was released -- and with the never-ending Iraq War still going -- verses like the following ring especially true:
What I'm trying to say is
It's time
To get in the way
It's crazy
That this thing is still going on
I can't believe
This thing's still going on
And it goes
Na na na na na na
I hate the war
Na na na na na na
I hate the war
Na na na na na na
I hate the war
-- "I Hate The War" (written by Greg Goldberg, on The Ballet's Mattachine!)
