What determines if a song is an "Oldie"? And how long does it get to be an oldie, before it's replaced by new-oldies? Will there be a next-generation of oldies music? Will we ever hear, "And here's one from the vault, 'Dirty Pop' by N*Sync"? Or will we be grooving to the Bay City Rollers forever?

As a side note, I'm convinced that the city of Chicago is obsessed with Elton John. Flip on 93.9 for an hour - you'll see what I mean.
