"Happy" by Pharrell Williams

"Happy" was written for the Despicable Me 2 soundtrack by Pharrell Williams. Pharrell came up with the idea for the lyrics by asking himself what being in a good mood truly feels like.

It might seem crazy what I'm about to say
Sunshine she's here, you can take away
I'm a hot air balloon, I 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, give me all you got, don't hold 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

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

Happy, bring me down
Can't nothing, bring me down
Love is too happy to bring me down
Can't nothing, bring me down
I said bring me down
Can't nothing, bring me down
Love is too happy to bring me down
Can't nothing, 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
