Hello! After watching "The Wrecking Crew" on Netflix recently I am interested in purchasing The Beach Boys' Pet Sounds for the first time. I see it is included twice on iTunes with one being a very recent release including both stereo and mono tracks. Are the mono tracks must haves? Seems like kind of a pain to have to delete half the tracks each time I download. I guess mono is big these days on early sixties reissues. Won't be long before the Beatles are offered in mono on iTunes also.
