A friend sorts his records in an interesting way: not by name or genre, but by which musicians are friends with each other. That means some shelves are very crowded, and I’m imagining a few notorious artists have plenty of room all to themselves.
It’s possible that we sort the folks in our lives this way as well. The people who can be counted on, who are part of a larger circle, who are dynamic or interesting or selfish… lots of shelves, available to anyone willing to put in the work (or not).
