I don't know, but I find it interesting that the 70s, when buildings looked horrible and so did cars (at least American ones), were also the time that produced some of the greatest music, such as Led Zeppelin and Pink Floyd. Contrast that to today, where we rightfully recognize that 70s architecture was crap and cars look pretty good in general, yet all music made since 2000 is utter crap and there's definitely nothing coming out as seminal as Led Zeppelin IV or Dark Side of the Moon.
