How does this wiki keep crossing over with my Doctor Who YouTube life? First we had a post which asked whether the 8th Doctor should come back on TV, of which I had watched someone say in a YouTube video the previous day, and now we have this! I saw a comment on a YouTube video that said 10s theme should've been "All the Strange Strange Creatures"! :O

I'd say the Doctor Forever as it plays many, many times in key Tenth Doctor moments throughout his last two series; All the Strange, Strange Creatures plays in other unrelated scenes as a kind of action theme; and while The Doctor's Theme Series 4 is literally called The Doctor's Theme, I personally consider it The Doctor's Theme as a whole as it plays in other Doctor's eras too. The Doctor Forever, to me at least, is just The Tenth Doctor's Theme.
