Baby, look at me and tell me what do you see?
You ain't seen the best of me yet
Give me time, I'll make you forget the rest
I've got more in me, and you can set it free
I can catch the moon in my hand
Don't you know who I am?
Remember my name
.
Sex! We're gonna live forever
I'm gonna learn how to fly (High!)
I feel it coming together
People will see me and cry
Sex! We're gonna make it to heaven
Light up the sky like a flame
Sex! We're gonna live forever
Baby, remember my name
(Remember, remember, remember, remember)
(Remember, remember, remember, remember)

in quoting the Irene Cara lyric "we're gonna live forever" when she recently died?

Yikes! Nobody told me! http://en.wikipedia.org/wiki/Irene_Cara#Personal_life_and_death

Well, "Her MUSIC's gonna live forever."

The song titled  "We are gonna live forever" in and of itself is an irony even if the person who wrote it were still living..  

I think you're exaggerating.
