I'm a sucker for the opening song of Dr. Who. I think it's because it sets such a creepy mood; of course then you start watching the show and get so completely confused you forget it, but whatever. I've watched many Tom Baker episodes and that's it - so I wouldn't call myself a huge fan of Dr. Who...more like a huge fan of the concept of Dr. Who. If that makes sense. Anyway, enjoy the theme songs from every era of the show.
