Most profound lyric personally?

"Was it love, or was it the idea of being in love?"

Short and simple, but has deep meaning.

I can see the similarities.

"If you negotiate the minefield in the drive and beat the dogs and cheat the cold electronic eye, and if you make it past the shotguns in the hall, dial the combination, open the priest hole and if I'm in I'll tell ya (what's behind the wall)...there's a kid who had a big hallucination, making love to girls in magazines, he wonders if you're sleeping with your new found faith. Could anybody love him? Or is it just a crazy dream? And if I show you my dark side will you still hold me tonight? And if I open my heart to you, show you my weak side, what would you do? Would you sell your story to Rolling Stone? Would you take the children away and leave me alone?"

Possibly "Wish You Were Here", for personal reasons.

On the non-Floyd front, the last section of "You Set the Scene" by Love and "Do You Realize??" by the Flaming Lips.

indeed.

'above the planet on a wing and a prayer
my grubby halo, a vapour trail in the empty air
across the clouds i see my shadow fly
out of the corner of my watering eye

Threw you the obvious
And you flew with it on your back
A name in your recollection
Down among a million, say:
Difficult enough to feel a little bit
Disappointed, passed over.
When I've looked right through,
To see you naked and oblivious
and you don't see me

Well I threw you the obvious,
Just to see if there's more behind the
Eyes of a fallen angel,
Eyes of a tragedy.

Here I am expecting just a little bit
Too much from the wounded
But I see,
See through it all,
See through,
And see you.

So I threw you the obvious
Do you see what occurs behind the
Eyes of a fallen angel
Eyes of a tragedy

Well, oh well..

Apparently nothing.
Apparently nothing at all.

You don't
You don't
You don't see me
You don't
You don't
You don't see me
You don't
You don't
You don't see me
You don't
You don't
You don't see me at all

3 Libras by A Perfect Circle.

"Remember how she said that we would meet again some... sunny day?
Vera... Vera...
What has become of you?
Does anybody else in here feel the way I do?"

To me it doesn't just apply to any individual person, but when going through hell it also feels like waiting/hoping/dreaming of being back in the life you used to have, being with the people you used to be with and being the person you used to be before you were in such a dark hell of a time. Kind of like how Wish You Were Here is about wishing you were the person you were before a certain period in your life which I could relate to the same way as I do with Vera.

The 'Cloudless everyday...' part of Echoes.

I couldn't agree with you more.

The first verse of Zappa's "Bobby Brown Goes Down", while not profound, is shockingly powerful to me (just the last part mind you):

"Hey, there people I'm Bobby Brown,
they say I'm the cutest boy in town!
My car is fast, my teeth are shiny,
so tell all the girls they can kiss my Heini!
Here I am at a famous school,
I present sharp and I'm actin' cool.
I've got a chearleader here wants to help
with my paper - let her do all the work
and maybe later I rape her!"

Even in darkest Scotland i can relate to that.

Lyrics from WYWH (the song, not the album)

Pigs (Parts one and two)

I think that Time is the best for the PF lyrics

'Just a Phase' by Incubus has the best non-PF lyrics

a thought came to me about the song "Lost For Words" so I found a forum about lyrics.
When I first read the lyrics and heard the song, these lines stood out:
"So I open the door to my enemies / And I ask could we wipe the slate clean? / But they tell me to please go **** myself / You know you just can't win."
at first, I thought they were HORRIBLE, at least when compared to the rest of the TDB lyrics. they had managed to stay coherent and poignant, then all of a sudden here comes this lyric that sounds like a high schooler wrote it. But the more I thought about it, I began to accept this lyric as a down-to-earth look at reality, desperate to get the point across in a beautiful kind of way.
And it also became a personal lyric, as like the rest of us i've encountered several idiots who would rather let a feud continue. again it's all about communication I guess.
