Many things once thought worthless—vinyl records, Brutalism—have grown in value. The Internet, which leaves no take unturned, has been predicting a compact disc comeback for years. After seeing what my lost Felt CD was now selling for, I began checking the prices of the CDs I’d held onto. A solo album by Kevin Rowland, of Dexys Midnight Runners, turns out to be worth $100 to $200 on Amazon. A couple Alex Chilton discs fall within the same price range. I was pleased, but scandalized too; I’d been so negligent with this treasure.
