I do remember that
Yeah its weird how it was billed that way when there were only a few real rock songs on the album. Mostly "2+2=5". I loved it at the time for the more diversity of sound (wasn't really pleased with "back to rock" stuff at the time, I enjoyed the experimentation) but nowadays its weirdly dull in spots where Radiohead was never dull before.
Maybe more rock would have spiced up the album a bit more instead of stuff like "Scatterbrain", "We Suck Young Blood", "Punch Up At The Wedding", "The Gloaming" etc - mid-tempo unmemorable type stuff
