Lyrics:

Sarah:
Disco dancing with the lights down low
Cheryl:
Beats are pumping on the stereo
Neighbours banging on the bathroom wall
Sarah:
Sayin' 'crank the bass, I gotta get some more'

Nadine:
Water's running in the wrong direction
Kimberley:
Got a feeling it's a mixed-up sign
Sarah:
I can see it in my own reflection
Cheryl:
Something funny's going on inside my mind
Nadine:
I don't know what is pushing me higher
It's the static from the floor below
Nicola:
Then its drops and catches like fire
Sarah:
It's the sound I, it's the sound I know

All:
It's the sound of the underground
The beat of the drum goes round and around
In to the overflow
Where the girls get down to the sound of the radio
Out to the electric night
Where the bass line jumps in the backstreet light
The beat goes around and round
It's the sound of the under, sound of the underground

Kimberley:
Chain reaction running through my veins
Cheryl:
Pumps the bass line up into my brain
Nadine:
Screws my mind until I lose control, oh
And when the building rocks I know its got my soul

Water's running in the wrong direction
Kimberley:
Got a feeling it's a mixed-up sign
Sarah:
I can see it in my own reflection
Cheryl:
Something funny's going on inside my mind
Nadine:
I don't know what is pushing me higher
It's the static from the floor below
Nicola:
Then its drops and catches like fire
Sarah:
It's the sound I, it's the sound I know

All:
It's the sound of the underground
The beat of the drum goes round and around
In to the overflow
Where the girls get down to the sound of the radio
Out to the electric night
Where the bass line jumps in the backstreet light
The beat goes around and round
It's the sound of the under, sound of the underground

Nadine:
I don't know what is pushing me higher
It's the static from the floor below
And then its drops and catches like fire
It's the sound I, it's the sound I
It's the sound I, it's the sound I know

All:
It's the sound of the underground
The beat of the drum goes round and around
In to the overflow
Where the girls get down to the sound of the radio
Out to the electric night
Where the bass line jumps in the backstreet light
The beat goes around and round
It's the sound of the under, sound of the underground

The bass line jumps in the backstreet light
It's the sound of the under, sound of the underground
The bass line jumps in the backstreet light
It's the sound of the under, sound of the underground
