Ok, I confess, I still like ABBA. The 70's answer to cheesy pop.
It's funny how you define ABBA. I am 50 y.o. now, and I remember myself very well growing up in the former USSR of the early- and mid-1970's. To me and many of my friends, actually, "ABBA" was a betrayal of things that we held dear: smashing hard rock of bands like "Deep Purple," "Uriah Heep," and the like. (I know, you probably never even heard about them.) We used to listen to tapes of Deep Purple and Uriah Heep smuggled from God knows where, and to us, that was the ultimate revolution... ABBA was "square," pretentious, smelling of expensive perfume store, dumb, completely un-"revolutionary" - even though "hip" and of course Western.
