Lyrics:

Hey, hey, hey
Hey, hey, hey
Every time I get the feeling I'm sane
Jealousy walks in and cuts me down again
Just like the enemy in my brain
Just like the enemy in my brain
Hey, hey, hey, hey, hey
(Jealousy) it's driving me insane
(Jealousy) jealousy, jealousy is a curse
(Jealousy) the enemy in my brain
(Jealousy, yeah)
Keeps coming on just like a poison in my veins
A suicidal sweat and the teardrops fall like rain
Just like the enemy in my brain
Just like the enemy in my brain
Hey, hey, hey, hey, hey
(Jealousy) it's driving me insane
(Jealousy) jealousy, jealousy is a curse
(Jealousy) the enemy in my brain
(Jealousy, yeah)
Fear, fear, fear, fear
Ooh-ooh-ooh, ooh, ooh
Ooh-ooh-ooh, ooh, ooh
Like an enemy in my brain
Makes me feel so strange
(In my brain)
When it's in my head
I get confused
I abuse
And I don't know what to do
Fear
Fear

Hey, hey, hey, hey, hey
(Jealousy) it's driving me insane
(Jealousy) jealousy, jealousy is a curse
(Jealousy) the enemy in my brain
(Jealousy, yeah)
Hey, hey, hey, hey, hey
Jealousy (in my brain) woo
Jealousy (in my brain)
Jealousy (in my brain)
Jealousy, yeah (in my brain)
Jealousy (in my brain)
