Music Production Glitches and Errors

I spent an unhealthy amount of time reading through this Reddit thread on Production Glitches and Errors in Popular Music - like the major obscenity at 55seconds in Louie, Louie or the tempo slowdown during What's The Frequency, Kenneth?. The list is long and completely fascinating from top to bottom. It event spawned its own subreddit if you enjoy it as much as I did.
