The way it's sort of framed in my head is this....

Back in the brick and mortar days you had individual record stores. Some were general music, others were specialized. I had to jump in my car and visit these stores. I certainly couldn't find the entire library of all music in a single store, but if I visited every record store in the cou try, I probably could get close.

The record stores are the relays hosting feeds. My car is whatever client app I'm using, connecting me to various stores/relays.

It's not the most efficient nor does it provide a whole picture. But as a user, I can only listen to one song at a time. I don't want access to everything all at once. I want to find specific songs or shows upon demand, or else sort and shuffle by genre. I think this enables it without providing more than what's realistically necessary from a end user standpoint.
