[Hook: Trey Songz]
Everything I ever said
Everything that I have done
Tryna show 'em it's my time
Building mansions in my mind
Now that's all so yesterday
I'm just lighting up my fire
Tell the world I'm saying goodbye
You ask me why...
I'm building castles in the sky
I'm building castles in the sky

[Verse 1: B.o.B]
I use to ride around town in a watchu call it
Looking like a demo rapper
Feeling like a dusty wallet
Getting fired, then hired, then refired
The idiots guide to how to build an empire
I show you how to stunt show you how to pop
Gotta watch from my wrist and a watch for my paps
Ballin' from the baseline, bottom to the top
Got bullets on speed-dial yeah I call shots
Now you can't act like you never heard of me
Cause I'm so third degree, everyday I'm burning leaves
I'm in my castle and I'm never coming down
They always said I had my head in the clouds, HA!

Tryna show 'em it's my time
Building mansions in my mind
Now that's all so yesterday
I'm just lighting up my fire
Tell the world I'm saying goodbye
Why...
I'm building castles in the sky
I'm building castles in the sky

[Verse 2: B.o.B]
I use to fantasise about the badess girl I couldn't get with
Couldn't get her number couldn't even get her digit
Then I saw the light now my nights are quite explicit
I'll be lost inside the ganja woulda sworn I went missin'
Got bills paid, got the whole hood saying damn Bobby Ray
Came a mighty long way
No GPS on star or navigation
We some self made niggas shout out to my operation
It started in my mind then it started takin' shape
I still cannot believe that these events are taking place
Uh, I'm in my castle and I'm never coming down
It's no wonder why my head is in the clouds, ha!

I'm building castles in the sky

[Bridge: B.o.B]
Building castles the size of collesiums
Thirty thousand feet up, I swear you gotta see 'em
Cruising altitude with a foolish attitude
Headed for the moon maybe Mars, maybe Venus

Cruising altitude with a foolish attitude
