Not sure if many of you have seen this or not, but just in case, you gotta check this out.
From the crazy awesome NicoNico Douga community to youtube comes a massive medley of over 120 minutes of continuous Castlevania rock remixes spanning the entire lineage of the series from Akumajou Dracula Arcade to the modern HD titles. No game is unrepresented, even the GameBoy titles and the the SD parody game Boku Dracula Kun/Kid Dracula.
If you like gothic rock even a little bit, this is worth not only a listen, but a download. mp3 is included with the video.
Enjoy!
