[Originally by Girls Aloud]
Disco dancing with the lights down low
Beats are pumping on my stereo
Neighbour's banging on the bathroom wall
He's saying crank the base I gotta get some more
Water's running in the wrong direction
Got a feeling it's a mixed up sign
I can see it in my own reflection
Something funny's going on inside my mind
Don't know what is pushing me higher
It's the static from the floor below
And then it drops and catches like fire
It's a sound I, it's a sound I know
It's the sound of the underground
The beat of the drum goes round and around
Into the overflow
Where the girls get down to the sound of the radio
Out to the 'lectric night
Where the bass line jumps in the back street light
The beat goes around and round
It's the sound of the under, sound of the underground
Chain reaction running through my veins
Pumps the bass line up into my brain
Screws my mind until I lose control
And when the building rocks I know it's got my soul
Water's running in the wrong direction
Got a feeling it's a mixed up sign
I can see it in my own reflection
Something funny's going on inside my mind
Don't know what is pushing me higher
It's the static from the floor below
And then it drops and catches like fire
It's a sound I, it's a sound I know
It's the sound of the underground
The beat of the drum goes round and around
Into the overflow
Where the girls get down to the sound of the radio
Out to the 'lectric night
Where the bass line jumps in the back street light
The beat goes around and round
It's the sound of the under, sound of the underground
I don't know what is pushing me higher
It's the static from the floor below
And then it drops and catches like fire
It's a sound I, it's a sound I,
It's a sound I, it's a sound I know
It's the sound of the underground
The beat of the drum goes round and around
Into the overflow
Where the girls get down to the sound of the radio
Out to the 'lectric night
Where the bass line jumps in the back street light
The beat goes around and round
It's the sound of the under, sound of the underground
Where the bass line jumps in the back street light
It's the sound of the under, sound of the underground
Where the bass line jumps in the back street light
It's the sound of the under, sound of the underground
