How in the world people have time to do this or the motivation to do so is beyond me. Some dude decided that he would get ALL the records the Beatles ever created (update: in the UK, sorry), mash them up all together, compress them into an hour-long mp3 and send it around the web for all to hear. I have no clue how long it took this guy to do this - or why. BUT what I do know is that if I was falling down Alice's rabbit hole for an hour, it would definitely sound something like this.
Extra points! - What song starts playing around the halfway mark??
