Chorus:
        Cmaj7
Because I’m happy
Clap along if you feel like a room without a roof
        Bmaj7 
Because Im happy
Clap along if you feel like happiness is the truth
        Emaj
Because Im happy
Clap along if you know what happiness is to you
        Cmaj7
Because Im happy
Clap along if you feel like that’s what you wanna do




Bridge X2:

Palm mute Emaj* for the whole bridge.

Bring me down
Can’t nothing bring me down
Your love is too high to bring me down
Can’t nothing bring me down
I said...

[Verse 1]

It might seem crazy what I’m 'bout 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

[Chorus]
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

[Verse 2]
Here come bad news talking this and that
(Yeah!) Well, give me all you got, 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...

[Chorus]

[Bridge x2]
Bring me down
Can’t nothing bring me down
Your love is too high to bring me down
Can’t nothing bring me down
I said...

[Chorus]
[Bridge]
[Chorus]
