Mine no doubt at all would have to have as it's theme already 'Downtown' by Petula Clark.

That song has helped me already through some really personally low times.
As a soundtrack likely more of her songs which contain the great optimistic lyrics expressed through her vocals could make the rest of the story of my life so far.

Another of her songs which would sum up a lot of how I feel and think too would be 'Who Am I', an amazingly simple pop song with really inspiring lyrics like most of her songs contain anyway.

That is what I would choose anyway.
