When I was a kid I would take one tape deck, hit record and record a rhythm guitar track. Then I would play that track while hitting record on another tape deck and overdubbing the next part over it. I would continue this process and in doing so add more tracks to my recording while making the sound quality worse and worse.
It sucked. But I loved it.
This is the digital modern equivalent. It still sounds like crap, but I wanted to show all the young musicians who are spoiled by garage band etc how good they have it :)
