i rekon its about the growth of music radio (as opposed to boring talkback radio) and how it all began with rock and roll. "Who writes the wrecking ball in two wild guitars" - rock and roll dystroyed a lot of society's 'morals', 'values', and preconceptions of what "acceptable" music was. it was one of the biggest inspirations for the 1950-60's cultural revolution. so where we are today is all because of rock and roll, hence "we built this city on rock and roll"
