I noticed recently that in a lot of pop songs, when they talk about love, you expect it to be about a man and a woman (or 2 humans more generally) and because of that expectation we can actually miss the message being conveyed.
There is a connection made between love/heart and freedom.
The way I see it, there are mainly 2 things that prevents us from reaching the heavens, the dome and "gravity", at least symbolically, two things put in place by God, "gravity", the G force could be seen as the God force, keeping us down here, that's why the wings are usually associated with freedom and the divine and can be found on angels or Hermes for instance. The trannies having butterfly tattoo makes sense from this perspective, the caterpillar crawls and after a transformation process, grows a pair of wings.
To summarize, freedom as in free dome of God.
Is it about the love of a fallen angel who rebelled against god? is it about the love of the embodiment of freedom? I don't know but it is love from a pure heart as we will see in example 6)
I will give you a few examples to illustrate this:
1) The Black Eyed Peas - Meet Me Halfway
In the music video, she's lying on the ground but the way it is portrayed, you can see the stars behind her. Her heart is preventing her from going any further.LYRICS
Can you meet me halfway, right at the borderline
Is where I'm gonna wait, for you
I'll be looking out, night n' day
Took my heart to the limit, and this is where I stay
I can't go any further than this
I want you so bad it's my only wish
2) Gwen Stefani - The Sweet Escape
They spit it out here, she wants to escape her cage and become God of her world.LYRICS
If I could escape
and recreate a place that's my own world.
And I could be your favorite girl
Forever, perfectly together
And tell me, boy, now wouldn't that be sweet?
We can see that a dog (God) is holding the key of her cage. I think it is not the same key in the second shot, it looks like a dragonfly, a winged insect, while in the first picture it looks like a cross. She also says that she acted cold, something we will encounter again in the next examples.
3) Nelly Furtado - Say It Right
She doesn't talk about love but we could infer that this is what she's talking about, she's also very cold.LYRICS
...
You don't mean anything at all to me
But you got what it takes to set me free
...
From my hands I could give you something that I made
From my mouth I could sing you another brick that I laid
From my body (from my body) I could show you (I could show you)
A place (a place) God knows (God only knows)
You should know, space is holy (Oh oh oh oh)
Do you really wanna go? (Three, four)
