Timelord rock, if you haven't already guessed, is music about Doctor Who. Yes, there are people out there who love that fictional TV program so much that they write music about it. (I am not one of those people, but that is only because I am quite honestly tone deaf. I would if I could.)
Notably the best music ever.
