Max Provenzano - Shake It Up

Yuh, mmm
Once upon a time
I became nine
I learned how to rhyme
But now I know how to burst
It's been a long time since then

I trenched, to learn my perspective
Ohh, ooh

Let's shake it up, up, up
Let's shake it up, up, up
Oh yeah, oh, oh, yeah
Oh, oh, yeah
Shake it up, we go

When I used to say "hi"
Now i stop to say "sup"
I used to say "boo, boo"
Now I say it's a cut
Many things change

{The rest: ?}
