Song: Happy
Artist: Pharrell Williams

It might seem crazy what I’m about to say
Sunshine she’s here, you can take a break
I’m a hot air balloon that could go to space
With the air, like I don’t care baby by the way

Because I’m happy
Clap along if you feel like a room without a roof
Because I’m happy
Clap along if you feel like happiness is the truth
Because I’m happy
Clap along if you know what happiness is to you
Because I’m happy

Clap along if you feel like that’s what you wanna do


Here come bad news talking this and that, yeah,
Well, give me all you got, and don’t hold it back, yeah,
Well, I should probably warn you I’ll be just fine, yeah,
No offense to you, don’t waste your time
Here’s why

Hey, come on
 

(happy)
Bring me down
Can't nothing bring me down
My level's too high
Bring me down
Can't nothing bring me down
I said (let me tell you now)
Bring me down
Can't nothing bring me down
My level's too high

Bring me down
Can't nothing bring me down
I said

Hey, come on

(happy)
Bring me down… can’t nothing…
Bring me down… my level's too high…
Bring me down… can’t nothing…
Bring me down, I said (let me tell you now)

Come on
