having been compelled to listen to it again, i will say that it sounds much less like a rumble than i recalled.
it's more of like a consistent whirring scratchiness..? you seem much more tolerant of it than i am though!
the music sounds GREAT and i know i'd listen to this way more often if that audio imperfection didn't run thru the entire album!
since it is, you know, the greatest album of all time.
