My pal Delme and I were discussing this piece of audio where someone put every Beatles song into one mp3 so you are hearing their whole catalogue simultaneously. I put together something similar on a way smaller scale five years ago, with the whole of the Beach Boys’ Pet Sounds album playing simultaneously. Delme’s a big metal fan, which tilted my brain in that direction, and lo! Here are all of the songs off Slayer’s Reign in Blood playing simultaneously. You are welcome.
