16. Atom Heart Mother
The longest Pink Floyd song (aside from Shine On You Crazy Diamond if it is pieced together). This is the first real epic that Pink Floyd ever attempted, and thus, is flawed in some ways, similar to The Fountain of Lamneth. However, the Funky Dung part as well as the finale are both very strong parts of the suite.
15. Dogs
One of the most overrated Pink Floyd songs ever in my opinion. The first couple minutes and the ending are both really good, but the middle ambient section completely drags the song down. It goes on droning for much longer than it needs to be. If they had cut out half or so of this section, the song would work much better. Still, it's an enjoyable listen from time to time, especially the guitar solo starting at about 3:50.
14. Any Colour You Like
Great underrated song from The Dark Side of the Moon. It is pretty much instrumental, but there is some soft singing in the background. The synth and the guitar solo are both highlights. Also, live versions of this song performed during 1975 improve the song even more. I highly recommend that you listen to those extended versions.
13. Hey You
Opening the second disc of The Wall, Hey You is definitely one of the highlights off of the album. Like the rest of the album, it is extremely dark in tone, but it works to its advantage. I really like the contrasting of Gilmour's softer and more relaxing vocals and Waters' higher pitched singing. The part directly after the guitar solo has an awesome chord progression.
12. Us and Them
Us and Them is the longest song off of The Dark Side of the Moon. Aside from the annoying background singers in the chorus, which sort of kill the very soft mood throughout the rest of the song, it is great. I'm a big fan of saxophone, and this song is no different. The two solos are very good, with the second one being slightly stronger than the former.
11. Run Like Hell
While this is not one of Pink Floyd proggier songs, it is still performed amazingly well. The slightly dampened(?) guitar sound fits great with the "Run, Run, Run" chant as well as the echoed vocals that constantly switch through each channel. I was never a fan of the sound effects at the end, but luckily the song doesn't fade out on it like Another Brick in the Wall (Part II) and ends on a hard chord.
10. Pigs (Three Different Ones)
The second song off Animals in this update. This song suffers from following pretty much the same chord progression throughout the entire song, however, the chords are constantly being improved and experimented on. The talk box solo is quite cool, but the best part is the ending guitar solo, which is one of my favorite Gilmour solos ever. It's awesome that Pink Floyd extended this song during live performances, similar to Any Colour You Like.
Here's my update. Again, my apologies for the very delayed. I'll really make an effort to not forget about this and finish by the end of the week, but obviously no guarantees. Hope you enjoyed reading these so far.
