I think these are the lyrics to most of the Pink Floyd releases. They are listed after which year they were released, starting at the very beginning in 1967 with Piper at the gates of dawn and ending in 1994 with the Division Bell. The reason that i did not include Delicate sound of thunder and P.U.L.S.E is simply that they are both live albums, no new songs in other words.
