Are these lines something you would actually say to somebody? That's the question I always ask myself when writing lyrics as opposed to poetry that isn't meant to be set to music.
The equation of transcendent love to flame is so overdone that the fires have gone out. You really have to work at it to say something new. Look at what you have...what exactly about the look in the eyes of the object of adoration makes you burn, and what do you mean by burn, exactly? Describe those...try to avoid smoldering glances and other generic phrases.
Here's an example:
I Can't seem to get you out of my head
I can't quench the flame in my brain
my heart has started beating fire instead
my heart pumping gas through my veins
that look in your eyes when you smile that way
your glances to me are like higher octane
say more about you than any words can say
and your smile is like nitromethane
lol...you could croon this to Tony Stewart or someone like that
here's another:
I Can't seem to get you out of my head
My thoughts are afire with desire
my heart has started beating fire instead
There's nothing can put out this fire
that look in your eyes when you smile that way
My body's on fire from head down to toes
say more about you than any words can say
So why don't you unreel your hose?
ok...slightly vulgar but why not? If the object of your affection is (insert pornstar name here) that last could work. The point is to consider what you're saying in greater depth than you have in this lyric. You can be subtle or come right out with it...but find a metaphor that works and run with it.
Is your love like a forest fire? A campfire? Is it so all-consuming that it sets the whole world on fire? Use the imagery.
If it's worth saying, it's worth saying well
