Interesting comments and thanks for the feedback.

I would however have to disagree with saying it's tied down to the Doctor's deal. It describes his loneliness from the perspective of being one-of-a-kind, unique, isolated, etc... as in the last timelord and also describes his emotion for losing a loved one. Two very common and much experienced situations. Something that probably most people can relate to.

Films, tv series, soaps, music all immerse people in stories or situations that may well have been the writer's perspective / experience at the time and even when it's based on pure fiction more-often-than not allow the viewer to relate to it in someway.

I'm slightly perplexed as to how you can have come to this conclusion as the feedback I've had so far has been completely the opposite. However we're all entitled to our own opinion and if you can't relate to the lyrics or simply don't like it then that's fine. Life would be dull if we all liked the same things.
