Us and them
Pink Floyd Lyrics

(us, us, us, us) and them (them, them, them, them)
Life is a constant battle between "us" and "them", where "us" represents people on one side and "them" represents people on the other side of a divide (which could be based on social, political or economic differences).

And after all we're only ordinary men
No matter which side we belong to, we are all ordinary people with the same basic needs and desires.

Me and you (you, you, you), God only knows
The differences between "us" and "them" are often arbitrary and beyond our control, but ultimately, everyone is a product of their upbringing and experiences.

It's not what we would choose (choose, choose) to do (to do, to do)
Most people do not actively choose to be part of a certain group or to hold certain beliefs; these things are often thrust upon them by societal norms, traditions, and conditioning.

Forward he cried from the rear, and the front rank died, and the general sat, and the lines on the map, moved from side to side
People in positions of power often put others in danger to accomplish their own goals or objectives, and the lines that divide "us" and "them" are often manipulated by those in power for their own gain.

Black (black, black, black) and blue (blue, blue)
People on both sides of a divide often experience pain or mistreatment, whether it is physical, emotional, or psychological in nature.

And who knows which is which and who is who
The lines between the two opposing sides can often blur, and it can be difficult to tell who belongs to which side, or who is right or wrong in a given situation.

Up (up, up, up, up) and down (down, down, down, down)
Life is full of ups and downs, and the conflicts between "us" and "them" are just one small part of a larger cycle of events.

And in the end it's only round 'n round (round, round, round)
Despite all the conflict and tension, the world keeps turning and history just repeats itself, perpetuating the cycle of "us" and "them".

Haven't you heard it's a battle of words, The poster bearer cried, "Listen son", said the man with the gun, There's room for you inside
Many conflicts start as a "battle of words", with each side trying to outdo the other, but this can escalate to violence and aggression. Those who are on the sidelines or who are not actively involved in the conflict often become collateral damage or are recruited to one side or another.

"I mean, they're not gonna kill ya, So if you give 'em a quick short, sharp, shock, They won't do it again. Dig it? I mean he get off lightly, 'cause I would've given him a thrashing, I only hit him once! It was only a difference of opinion, but really, I mean good manners don't cost nothing do they, eh?"
This spoken portion of the song highlights the futility and absurdity of violence, and how people often justify their actions with flimsy or misguided reasoning.

Down (down, down, down, down) and out (out, out, out, out), It can't be helped that there's a lot of it about
Many people are marginalized, oppressed or left behind by society, which contributes to the growing conflict and tension between different groups of people.

With (with, with, with), without, And who'll deny it's what the fighting's all about?
People often fight over resources or opportunities that are perceived to be limited or scarce, leading to a divide between those who have them ("with") and those who do not ("without").

Out of the way, It's a busy day, I've got things on my mind, For the want of the price, Of tea and a slice, The old man died
The song ends on a somber note, with the realization that many conflicts arise from trivial or petty differences, and that ultimately, these conflicts can have dire and tragic consequences.
