Well, you'd have to wade through a lot of pop, that much I can tell you...but you might like some of it. Most of what I bring home I do play, but some of it is simply better pressings of older stuff I already own up north, which isn't available to me at the moment. So much '50s & '60s mainstream 'adult' pop can be found at thrifts and anywhere used records are sold for a quarter to a buck, generally, and if you're willing to wade through the crap, you'll find plenty of minty or close pressings, mono or stereo. You'll stumble on some rock at times, but the better stuff mostly finds its way to dealers who charge more than some are willing to pay.
As for more guilt, here's one from 1960 that in fact sold pretty decently, though it's forgotten today. For those who remember Preston Epps' "Bongo Rock" from 1959, here's a whole album of such enjoyable noise, from late 1960:
