Depending on whether your going for the actual meaning of the songs/albums, or whether it's just your interpretation, a lot of it lies in your grasping at a concept that just isn't there.

We'll start with Dark Side

Speak To Me isn't about an infant, maybe to you, but in actuality it's just a little piece made by Rick Wright. "I've been mad for facking years, probably ages. I've always been mad, I know I've been mad..." doesn't really relate to infancy.

Breathe is an observation of materialism and lack of a heart a soul, kinda.

On The Run isn't about anything, it's instrumental

Time is about wasting your time, and looking back realizing you wasted your time.

GGITS isn't about anything, it's an instrumental

Money is about money

Us and Them is pretty much what you said

Any Colour You Like is an instrumental

Brain Damage is about "defending the notion of being different" - Roger Waters

Eclipse just kind of sums up the bittersweet feel of the album. "Everything under the sun is in tune, BUT the sun is eclipsed by the moon".

Wish You were Here is about the band pretty much.

Shine on - Very blatantly about Syd

Machine - Recording Industry

Cigar - Recording Industry

Wish You Were Here - Syd

The Wall is a story about a man named Pink who collapses under the struggles placed in his life. He builds a wall around his emotions and isolates himself from the world around him.

I really don't consider Meddle a concept album. I think Echoes shows their transition into songs that observe 1970's society.

But anyway......This shit is just off the top of my head.
