This is just my theory, but I think it's about someone who is an assassin possibly? And he gets fucked over by someone on the inside. Some of the lyrics that lead me to believe this are,
With a thousand lies, and a good disguise
This leads me to the conclusion because it makes me picture someone who is there just blending in and has an elaborate cover up because he's getting ready to pull off some big job.
Now dance, fucker, dance
I never had a chance
They never even knew
It was really only you
This makes me think of the kid talking to his "boss" saying he took his life from him and brought him into the business and now he's exacting his revenge by shooting at him; hence the "dance, fucker, dance...I never had a chance" The "they never even knew it was really only you" makes me think of how no one would expect someone on the inside to be doing this to a kid.
There are also some parts about "someone is in your way, time to take him out, nice work you did, you're gonna go far, kid" That once again reminds me of the boss trying to reassure the kid he's doing good and would never expect to get fucked over.
I'm sure there's more, but I've only listened to the song about 15 times tonight since I got it about an hour ago. So, I'm sure my theories can be very vague and way off.
I apologize for the poor punctuation when describing the lyrics, but I didn't wanna take up more space by skipping a line each time. I'm just so fucking excited for this album, I've been waiting 1/4th of my life for this to come out. About 4 1/4 years, and I'm 18 so the math works :P But yeah I'm so excited and just wanna talk about this. So let me know what you think about my theories, or present your own!
