Cover art for Pigs on the Wing (Part 1) lyrics by Pink Floyd

this album is amazing. i can't just listen to 1 song, i have to listen to the entire album. in my opinion, i believe that the song is reference to how simple life for animals must be, in the sense that they don't have the same emotions and thoughts as humans do. animals just do what comes naturally to them and they can't comprehend the complexities/problems of life that consume humans.
