[bad word] baby time to play, you know I want it bad, you too
 Yeah baby its okay if it drives me mad, cuckoo
 Maybe I love it, maybe I need it
 Maybe there ain't no other way to try and please me

No matter how it all goes down, I just know I want you now

So don't you, don't you tell me no,
 (My necessary evil)
 Yeah I'm in control,
 (My necessary evil)
 Guilty pleasure is a way to go,
 (My necessary evil)
 So don't you get emotional,
 (My necessary evil)

Baby you ain't nothing but a necessary evil
 (My necessary evil)
 Baby you ain't nothing but a necessary evil
 (My necessary evil)
 Baby you ain't nothing but a necessary evil
 (My necessary evil)
 Baby you ain't nothing but a necessary evil
 (My necessary evil)

I should lose these wicked ways, I know this can't be good for you
 So tell me that you love these games, you don't mind being used do you?
 Maybe I love it, maybe I need it
 Maybe there aint no other way to try and please me

Yeah there might be [bad word] to pay, but right now I got it made

So don't you, don't you tell me no,
 (My necessary evil)
 Yeah I'm in control,
 (My necessary evil )
 Guilty pleasure is a way to go,
 (My necessary evil)

 (My necessary evil)
 Baby you ain't nothing but a necessary evil
 (My necessary evil)
 Baby you ain't nothing but a necessary evil
 (My necessary evil)

 (My necessary evil)

Take it to the heart or take it to the head
 I took it too far, going back on what i said
 Feels good till its done, then I'm on [bad word] 
 I'm dangerous like a loaded gun

So don't you, don't you tell me no,
 (My necessary evil)
 Yeah I'm in control,
 (My necessary evil)
 Guilty pleasure is a way to go,
 (My necessary evil)
 So don't you get emotional,
