I'm not implying the lyrics are great or anything. I'm just saying she didn't just pop Edgar Allan Poe's name for the heck of it. There's plenty of other stuff related to the poet in the lyrics. And even the unbolded parts, make perfect sense, according to The Raven's plot/meaning.
Kremlin means castle in russian, so the title probably relates to the setting of The Raven, which also occurs at dusk (or night, I don't remember).
Again, I'm not implying the lyrics are good. I don't care if they're good or bad anyway, to me it's the same.
