The Capitol Records Building Wonder can never be built. It needs the Recording Studio as a prerequisite. But the Recording Studio needs the Phonographs resource. Phonographs are built by the Phonograph Factory. But the Phonograph Factory goes obsolete at Mass Media. And the Capitol Record Building is only available at Mass Media. An easy solution would be to not have the Recording Studio need Phonographs which isn´t realistic anyway (something more modern than Phonographs like tapes or hard discs should work, too). Similar thing: To build a Local Radio Station you need Phonographs, too. But to build the Internet Radio Station you need a Local Radio Station. But at this time Phonographs will be for a long time obsolete and you can´t build new Radio Stations.
