Clap along if you feel like happiness is the truth

Because I'm happy

Clap along if you know what happiness is to you

I know I won't be lonely, baby

You're a dancing flame

You're not scared to lose control

Hey, soul sister, ain't that Mr. Mister on the radio, stereo

The way you move ain't fair, you know

Hey, soul sister, I don't want to miss a single thing you do

tonight

The way you work it, get me off the ground

I wanna scream, shout, and lose control tonight

Hey, soul sister, ain't that Mr. Mister on the radio, stereo

tonight
