Minecraft - Ender Dragon boss fight + custom songpack made by a friend

So my friend BlueClawRaptorGames made a songpack for Embassy, which has some sweet boss fight music from Terraria Calamity (namely The Devourer of Gods phases 1 and 2 themes). This video shows the Ender Dragon boss fight with said music pack active (very epik), as well as particularly pissed off Endermen, and me being bad lmao.
