[Verse 1: Ralph Tresvant]
Heart, beating strong
I was serious
My love was furious for you
Only you (Only you), oh baby
Darling I don't know why
I can't leave you alone
You thrill me to the bone
You're the one
Obsession (Obsession)
Ah, baby

[Chorus: New Edition]
Don't you know it was a crucial lovin'
Cru-cial
Crucial lovin'
Cru-cial

[Verse 2: Ralph Tresvant]
Chills, over me
Different from the rest
I won't settle for less
Hello
Won't take no (Won't take no)
Ah, baby
From now on, you and I
Stood the test of time
And still you're on my mind always
Night and day (Night and day)
Ah, baby
[Chorus: New Edition & (Ralph Tresvant)]
Don't you know it was crucial lovin'
(I never knew love could be so crucial)
Cru-cial (Ah yeah)
Crucial lovin' (Girl, you are my last time, sugar)
Cru-cial (Baby, you're the one)
Don't you know it was crucial lovin' (From now on, baby)
Cru-cial (Don't you know it was a crucial love)
Crucial lovin (Down to the, down to the bone)
Cru-cial (Hey, hey, hey)

[Instrumental Break]

[Bridge: Ralph Tresvant]
I have more than told you
Girl, I've got to show you
Feelings overload extreme
For the very first time
Girl, you are my last time
You have taken over me

[Chorus: New Edition & (Ralph Tresvant)]
Don't you know it was crucial lovin'
(Baby, I don't know why, oh)
Cru-cial (And you're on my mind every day)
Crucial lovin' (I never knew love could be so crucial)
Cru-cial (Ah, girl, yeah, yeah, yeah, yeah)
Don't you know it was crucial lovin'
(It shouldn't hurt me this way)
Cru-cial (You're the one! You're the one!)
Crucial lovin' (You're the one, you're the one for me)
Cru-cial (No one else)
Don't you know it was crucial lovin'
(Girl, this is my last chance)
Cru-cial (So I'm begging you)
Crucial lovin' (It's crucial; it's crucial!)
Cru-cial (Yeah)
Don't you know it was crucial lovin'
(Down to the, down to the, down to the bone)
Cru-cial (Down to the, down to the bone!)
