Yeah, let's go

Yo, I'm feeling it, the vibe is right
Got me feeling like I'm gonna take a flight
Let it go, yeah, you know I got it
So, we can go and take a trip to the moon

When we touch down, it's like we're having fun
Everybody just lets loose and have some fun
Yo, it's time to start something real fun
Just lay back and let me take control of your world

Got me feeling so electric and wild as I thrive
Get in the zone and you won't even notice the breeze
And I know that you feel it too, yeah
You and me, we can ride this feeling forever, forever
