[Verse 1: Illanoise]
My brain matters, I hate slackers, thinking they ill the first gay rappers
I take half of they brain out of they skull I bet they don't change it
How I'm way beyond what they understand and they hating on me, you fucking playing?
Naw, tell me what the fuck you saying, you think I'm weird and you're so amazing
It's laughable that you think that, that Jesus Juice I won't drink that
That's why I don't fuck with yo weak ass
All these local shows I don't need that
Those shitty mics that alt feedback
Everybody in the whole team is whack
And they fronting like they don't see that
Each one looking like they need rehab
Open 'em up, I don't givе a fuck
Most of 'em totally broke and they suck
Thinking thе industry's holdin' them up but the fact of the matter is, they don't know much
They just get fucked out of money, they dumb
Don't even notice it's happening, none
They just keep smiling, having their fun, making no money and asking for some
And it's funny as soon as I hear the verse, I can tell if they've been putting in work
Give 'em advice and they think you're a jerk
So we just laugh at 'em knowing it hurts
They need to slow it all down and reverse, but you know that they won't and it only gets worse
They shoulda studied the basics first, but they didn't and now it's just basic words

[Chorus: Grewsum]
Do you use your brain matter? (Matter)
Does your brain matter?
Do you use your brain matter? (Matter)
Does your brain matter?
Do you use your brain matter? (Matter)
Does your brain matter?
Come on man be honest, is it part of the process?
Do you use your brain matter? (Matter)
Does your brain matter?
Do you use your brain matter? (Matter)
Does your brain matter?
Do you use your brain matter? (Matter)
Does your brain matter?
Quit with all this nonsense, you're making me nauseous
[Verse 2: Grewsum]
Tell me, do you actually use your brain? Is that too insane or too damn strange?
For you to say, can you comprehend when I rock the pen, when I spew these flames?
You say I'm not, I'm not, I just wanna jot this
Maybe you're obnoxious, that's why I drop shit the hottest
How do you feel the content strikes up my conquests?
It's not a joke, it's not Andy Milonakis
How disdained should I use your brain matter or you just the same rapper with a chain tatted
Tired of this fake shit and caught up in the matrix
Tried to gain status and not getting any better
You act like some dumb fucks
Act up and we'll all let the gun bust
Might catch you my dick like a nunchuck (Woo)
Every day he won't shut the fuck up
So all you do is scream and yell
I'm a demon breaching hell
I survived in Hell's Kitchen
Ramsey ain't feeling well
'Cause I'm the heat messiah
I bring the beat that fire
I'm a fire-breathing dragon unleashed from Skyrim
I'm the hybrid of a Titan, a Lycan, and a pirate
'Cause I'm striking and I'm biting that booty when I find it
You think you matching with me, you'll be a casualty
'Cause when I rap on a beat I actually think, bitch
[Chorus: Grewsum]
Do you use your brain matter? (Matter)
Does your brain matter?
Do you use your brain matter? (Matter)
Does your brain matter?
Do you use your brain matter? (Matter)
Does your brain matter?
Come on man be honest, is it part of the process?
Do you use your brain matter? (Matter)
Does your brain matter?
Do you use your brain matter? (Matter)
Does your brain matter?
Do you use your brain matter? (Matter)
Does your brain matter?
Quit with all this nonsense, you're making me nauseous

[Verse 3: Twisted Insane]
I was all off on a date with a bitch getting wasted and I don't feel no pain
Chasing this coochie for days and I never got laid so I gotta use my brain
I don't need money, no I don't need watches, no I don't need big ole diamond chains
N***as that be thinking they be with it when they showing all that shit up in they video is motherfucking lame
The industry is a fucking joke (Yah)
I'd rather spend my time up in smoke (Oh)
You bitches be getting way up in hopes (Hope)
But never wanna get out and hustle though (Nope)
And that's when I be laughing at you bitches, knowing that you really 'bout to fuck up all your riches
I be murdering the microphone and do 'em vicious
Then put all them rest of their body in ditches
Hear 'em on the radio, they mumble talking jumbo, I don't really want it (Nah)
Rather be all by myself with weed up on the shelf and talking to the haunted (Yah)
I don't really get it, you be thinking that you with it but you really get so motherfucking weak
Every time I hit it, shit somebody passing blunts and I be thinking I don't wanna hear you speak
Twenty shells a week in the same city
Got married n***as sucking on the same titty
I post with the homies and the gang get me, four-fifths, more shit, n***a bang fifties
Yeah, they know this, I'm Insane
Coming out the trunk with some shit that'll bang
Time for my ears to go shit
Everybody else listen up to the sick in my brain
[Chorus: Grewsum]
Do you use your brain matter? (Matter)
Does your brain matter?
Do you use your brain matter? (Matter)
Does your brain matter?
Do you use your brain matter? (Matter)
Does your brain matter?
Come on man be honest, is it part of the process?
Do you use your brain matter? (Matter)
Does your brain matter?
Do you use your brain matter? (Matter)
Does your brain matter?
Do you use your brain matter? (Matter)
Does your brain matter?
Quit with all this nonsense, you're making me nauseous

[Verse 4: King Iso]
Uh, pushing through the lane, fuck a rest stop
That's how all you n***as fore-came through my mess, watch
Move, and you n***as on some games like an Xbox
Cruising, pull up on him, more bang after red drop
N***as get to wolfing on the Brain till they get popped
Put your car in Boston, bang like I'm Red Sox
N***as steady talking till I aim for the headshot
Does your brain matter? *gunshot*
I guess not
Now tell me who the fuck'll wanna go to war next
I done been there, done that like a war vet
Speed up when I creep up on you n***as in the Corvette
Then I gotta hit 'em with the venom like the vortex
Do you think he pressed like it was forceps
Like to work 'em out, I'll probably bring it to your doorstep
No religion dot up on your forehead
Pumping through your cortex, if I get life n***a I'ma eat the cornbread
Cortez Nike's with the 5-0-1s
Fee Fi Fo Fum here ISO comes
You was talkin' a lot of shit, don't bite your tongue
Knife to a gunfight then slice yo lung
I think it's exciting, I'm on one
Why mimic my life n***a? I'm so dumb
Invite n***as, see a scythe, well then I won't come
Life is a dyke riding a micro-thumb
Triv, on my mama I don't really understand you n***as
Man, pull that llama out and buck it at yo family members
You ain't in my lane, we ain't climbing the same ladder
N***a pull up on 'em, run it, they fucking and they scatter
They be talking, I be talking with choppers when they scatter
Turn that n***a to a zombie when chopping they brain matter
N***a brain (Brain, brain, brain)
