Happy by Pharrell Williams.

It might seem crazy what I'm bout to say
Sunshine she's here, you can take a break
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
Give me all you got, don't hold back
I should probably warn ya, I'll be just fine
No offense to you, don’t waste your time

(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

Bring me down, can’t do, bring me down, your love is too high
Bring me down, can’t do, bring me down, I said

(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

Bring me down, can’t do, bring me down, your love is too high
Bring me down, can’t do, bring me down, I said

(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
