The Cybermen still have the same musical theme they've had since Rise of the Cybermen/Age of Steele? I'm not really complaining, it's a great tune. But still, when Moffat took over there was a great purge of music from the RTD era, the Doctor's various themes were replaced, the Daleks got a new theme, and yet somehow the Cybermen theme stayed. And even now with the transition from Smith to Capaldi, I am the Doctor has been removed from the show proper (though still used in some trailers) and replaced with another new Doctor theme, and still the Cybermen keep the same theme they've had since 2006.
Does everyone just love that specific piece of music that much, or is there nothing else that says "Cybermen" more than that?
