The first one to come into my possession was The Wall. Other early ones must have been Dark Side, Meddle and Piper because I have all those on LP. Later on, Dark Side was one of the first CDs I bought when I got my first CD player. Secrets is actually from a dupe tape of an LP, but it still sounds pretty good.
Works is a compilation album that is not entirely redundant. The tracks that appeared on previous albums are not all entirely identical to the original versions. It also has a few tracks that were released only as singles and were not included on any albums. It also has one track ("Embryo") which is not a Pink Floyd track but Roger Waters only, and must have come from the Sounds from The Body sessions.
I also have a cassette of A Collection of Great Dance Songs which I bought because it has an alt version of "Money" (I ripped just that one song), and a two-cassette set of The Delicate Sound of Thunder that I bought because it was cheap. I haven't ripped it yet.
I would still like to get CD versions of Piper, Secrets, and Meddle, and I would still like to add The Final Cut to make it complete. I suppose I should also get More, for completeness, and Relics because it has a couple of tracks that were previously released only as singles or B-sides.
The side-long track "Echoes" from Meddle is one of my overall favorite Pink Floyd pieces, by the way. Favorite album? Probably a tie between Dark Side of the Moon and Wish You Were Here.
Also, back sometime around 1990 or so, KZEP played the entire live album
Album count: 415.
