Minecraft was a Rhythm Game Sub Urban Cradles

I spent over 100 hours creating this Minecraft world synchronized to the beat of Cradles by Sub Urban. My goal was to make this the most complex Beat Craft video I've ever made. Trickshots, redstone, parkour, explosions, it's got it all. Surprisingly, I was able to get a full take through the entire map without any mistakes.
A peak behind the scenes:
Sometimes I wonder if I am being inefficient when I put multiple days of work into something that will only be on screen for a few seconds. For example, the text reveal at the beginning seems like it should be simple and straightforward. Just drop some walls of sand to show the lyrics and you're done right? Turns out sand falls too slowly to reveal the words in time as the minecart passes by. Okay, let's rip that out and just use the create mod to flip up some flaps and reveal the words instead. Another problem, the Minecraft render engine doesn't immediately do visual block updates after a certain distance. Some of the words are too far from the minecart. Finally, by the third iteration, I discovered a trick to keep the text large, at a distance, and reveal instantly. While updating block data from a distance isn't immediately visible, updating entity data can be. Using the create mod, I activated cart assemblers before the player exists the nether tunnel at the start. This converts all the text blocking linear chassis into entities off camera. When the player exits the tunnel, I release the minecarts, dropping these massive walls of entities away to reveal the text. Iterations like this are frequent in my design process.
