Yes, the folks behind the counter at CD Warehouse are well-aware that their shop smells like donuts (blame the thin wall separating them from next-door Dunkin). No, you can't use the bathroom, so please don't ask. However, feel free to hit these music fiends with any and all questions -- if they don't know the answer, they'll find someone who does. CD Warehouse does an admirable job of buying mostly obscure, hard-to-find collectibles, keeping a steady stream of used stuff mingling with the big sellers. It's almost impossible for small independent retailers such as this to keep pace with department stores and online shopping, but CD Warehouse survives by taking in secondhand artifacts (we found Legendary Pink Dots and Violet Indiana on one visit) and offering them to the next savvy shopper -- keeping the circle of cool alive.
