Lyrics
The Chipmunks:
Yeah, I can't sit still, I can't slow down
I need something to do right now
I can't think straight, or concentrate
Without some screen to put in my face
I gotta move all my fingers (fingers)
Before my brain goes stiff
Everyone keeps saying I'm over-stimulated
Get busy, get-get busy
Get busy, get busy, get busy now
And all those voices in my head
Keep them occupied instead
Get busy, get-get busy
Get busy, get busy, get busy now
And all those voices in my head
Keep them occupied instead
Ooh-ooh-ooh-ooh, ooh, ooh
