歌词：Brenn Hill. What A Man's Got To Do. Caffeine.

Seven hundred miles before the sun comes up
My savin' grace is in my styrofoam cup
Every highway, every city
I think I've seen them all
I don't smoke tobacco and I don't drink alcohol

But baby caffeine, caffeine
Pour me a cup of that gasoline
Caffeine, caffeine
Tonight I'm flyin' lean and mean
And it's killin' me, savin' me, or somewhere in between
But I'm like a machine
On caffeine

When the white lines start to fade
My eyes get heavy as lead
And it feels like a hundred days
Since I last saw my bed
I'm lookin' for that neon sign like an angel in the night
To help me lose these old highway blues
'Til the mornin' light

It's caffeine, caffeine
Pour me a cup of that gasoline
Caffeine, caffeine
Tonight I'm flyin' lean and mean
And its killin' me, savin' me, or somewhere in between
But I'm like a machine
On caffeine

Take it hot, take it cold
Swallow it in a pill
I'll be back out on the road
Just as soon as I get my fill

Caffeine, caffeine
Pour me a cup of that gasoline
Caffeine, caffeine
Tonight I'm flyin' lean and mean
And its killin' me, savin' me, or somewhere in between
But I'm like a machine
I'm flyin' lean and mean, baby
I'm like a machine
On caffeine
