Meta on Metallica and Meaning

[chasingtides]

I've written a meta, The Thing That Should Not Be: Dean Winchester, Metallica, and H. P. Lovecraft. There are (very minor) spoilers for the last two episodes of the season. It's mostly a meta on Metallica lyrics and certain corresponding, inspiring novellas and short stories - and why, exactly, Dean should know them.

Heavy spoilers for "Shadow Over Innsmouth" (1936) and "Mast Of Puppets" (1986).
