Trock 

Trock, or Time Lord Rock, is a new genre of music based on The popular (and awesome) TV series, Doctor Who. Similar to the Wrock (Wizard Rock) craze, stemming from the Harry Potter books, Trock is really any kind of music but with lyrics based on Dr Who rather than Harry Potter.
It was "created" by the amazing Youtube user Nerimon

Trock On!
