Dusty oldies

A memory of WGCI: In addition to playing an appealing mix of old and new R&B, I was struck, when I visited Chicago in the '80s and early '90s, by how the station referred to an oldie as a dusty.  It's an interesting idea, actually, conjuring up the image of a dusty record being taken off a shelf and played on the air.  I've never heard any other station refer to oldies as dusties since then.  Decades later, though, I still remember the term and associate it immediately with WGCI.  That's effective marketing.
