Animals is my favourite Floyd album. The core of it, Dogs, Pigs, Sheep, are three of easiest 10s I could possibly give. This song is one of Floyd's heaviest, it contains some serious early metal riffage, and live versions are absolutely awesome (check the infamous Oakland show)! The line "wave upon wave of demented avengers marching cheerfully out of obscurity into the dream" is simply one of best lyric lines ever written. I could dissect this song inside out, but the ending lines "Have you heard the news? The dogs are dead! You better stay home, and do as you're told, get out of the road if you want to grow old" depict all the "people's" revolutions in history - the tyrant's reign ends, but some of the "people" become new masters. And you better subdue to them.

P.S. I don't have an inspiration for the next song, so I'll pass that on to next poster.
