They're known for their only-as-catchy-as-necessary beats and vague (sometimes confusing) lyrics.
This song, in particular, has quite a few different meanings (I guess) but I will share my own thoughts with you.
It appears to be about the existential crisis of the so-called "modern man" - humans following along with what is popular nowadays without really understanding the purpose of said materialism. We huddle together in lonely packs with our heads down and our shoulders up, not even attempting to question or wonder.
"In line for a number but you don't understand/like a modern man"
"I know we are the chosen few, but we're wasted"
"And you feel so right, but how come you can't sleep at night?"
These are just a few lines from the song that support my opinion.
Then again, in the end, that's exactly what it is - an opinion.
Maybe you should listen to it yourself, come up with your own thesis.
Well? What are you waiting for? I gave you the link - the rest is on you.
