Everyone loves to remix and adapt the famous overworld theme from The Legend of Zelda, but the franchise has its share of memorable dungeon themes that deserve their own share of attention.  Nintendo has released a video from the traveling The Legend of Zelda: Symphony of the Goddesses concert series in which the Royal Philharmonic Orchestra at the Hammersmith Apollo, London performs a medley of beloved dungeon songs from across the franchise.  It's just what you need on this Friday.  Be sure to pick up the boss key on your way to the inner sanctum or else you'll just have to backtrack.
