From Tardis Wiki, the free Doctor Who reference
We wouldn't need to take note of every time "I am the Doctor" is played in order to have an article about "I am the Doctor". The only difference between writing an article about a diegetic and an extra-diegetic thing is that the former is written as an in-universe article and the latter gets a {{real world}} tophat.
I think the real issue here is that we don't know the name of the piece.
