It's the song theory.

Why should they get 6 keys in 8 episodes?

(Not counting the season finale, because it will probably just be about the opening of the chest)

Rainbow Dash made a journal entry in the last episode, which isn't in this tweet list.

So it only can be the song which is the most plausible theory, in my opinion.
