Pablo Honey can't be saved, even with a different track order. Though the album does have some real stars imo. Stop Whispering, Blow Out (which is honestly one of their best songs), You, and Creep are all pretty good. And Coke Babies is a great b-side.
The Bends is perfect when it comes to track order and structure. Even Sulk is better in the context of the album, I think.
OK Computer is great until Fitter Happier. Fitter Happier is great, it's just that Electioneering is not. It's the first dud on the album, and without it I would have been much happier with the flow of this album. Plus, doesn't Fitter Happier to Climbing Up the Walls sound like a killer, no brainer transition? Gives it a perfect creepy vibe.
Kid A is almost perfect. The first half (up to Treefingers) is great, and Optimistic to In Limbo is amazing as well. But Morning Bell to Motion Picture Soundtrack...I never liked that. It's not fulfilling enough. I guess my point is this album needed it's Lucky, or it's Jigsaw, or it's GUtG, to bring it full circle, you know? I do love Morning Bell, but it doesn't work as a penultimate song.
Amnesiac. I've never been sold on this album. I think it's flow is stupid, not "experimental", just stupid. I can't stand to listen to this album in full because of transitions like Pulk Pull to YAWA, or Knives Out to Morning Bell/Amnesiac. Like Spinning Plates to LIaGH is a good ending to the album though, mostly because those songs are brilliant.
Hail to the Thief is actually one of my favorites. It's a mess in a good way, compared to Amnesiac. I think the ending could have been ironed out a bit more. Scatterbrain is a great song, but I don't like it before AWATD. I always thought Sail to the Moon would have been great right before AWATD.
In Rainbows is perfect. I think Down is the New Up would have been good after All I Need (the album lacks "fun" songs. to me this album is Radiohead's most serious and emotional work).
TKOL is also perfect. It's a natural progression, from Bloom (the most chaotic song on the album), to Separator (the most peaceful song in their career). It's also my favorite Radiohead album, so I may be a tad biased.
