I really like the 9th Doctor’s opening theme.

It’s bold and confident, without being overly-bombastic (which always smacked of desperation on Gold/the producers part….especially Ten’s disco-theme for season four). It has a somber singularity to it. Small and simple, yet bristling with subtle complexities. Much like Nine, himself. Thick with powerful bass and a driving rhythm, the heartbeats of the wounded Time Lord running through history. Steady and forever.
