Verse 1:
Come on, let's go crazy
Throw your hands in the air like you don't care
You're here, so sing it loud
And let your voice be heard

Sing, sing, sing it with me
Come on, let's make some noise
Sing, sing, sing it loud
You and me, together now

Life's a party, you're invited
Don't be shy, it's okay
You're beautiful, and so are you
You don't have to prove nothing to anyone
Chorus:
Sing, sing, sing it with me
Come on, let's make some noise
Sing, sing, sing it loud
You and me, together now
Bridge:
Yeah, we're all here together now
So let's have some fun and dance the night away
No one's perfect, we all make mistakes
But we can learn to love ourselves today
Chorus:
Sing, sing, sing it with me
Come on, let's make some noise
Sing, sing, sing it loud
You and me, together now
Outro:
So let's go crazy and dance the night away
Come on and sing with me now.
