this is related to my dinky cloud jukebox (https://github.com/pauldardeau/cloud-jukebox). that's a fancy
way of saying a bunch of mp3 files stored in swift.

i run it on a vps (droplet!) with 2gb ram and 40gb disk

i continue to work on my cloud jukebox thingie
primarily by adding more of my music collection to my little saio swift cluster on a vps
as part of my goal of moving completely away from itunes
i’ve been doing a lot more of that lately, and i completely filled up (100%) my loopback storage device
it’s configured with standard 3 replicas (default)
