Wendell,
Just compare Modern Times to Bob Dylan's "Oh Mercy", for example, take the track "Man in the Long Black Cold" and hopefully it will become clear what I mean about compression. I find Dylan's voice is uniformly loud clear and monotonous on Modern Times...sounds like compression but it might be bad miking....of course it may likely be an intentional "effect" rather than a mistake and some people may prefer it....to me it lacks dynamics of real music.
(There are often two points of view; Daniel Lanois messed up U2 sound IMHO but he was also praised for the sound "style" by many. So we may disagree simply due to preferences)
