If you click there, you'll see a list of Cabinet Pin releases. Most of them are unavailable at the moment. They're unreleases - those extremely limited 20th-of-the-month compilations - and they're only really up there for our own amusement (and to advertise the project to anyone who might want to contribute. e.g. you).
You can also download MP3s from some of the record pages. That has to count for something!
