You're forgiven if you didn't realize Uncle Sam's had a used-CD section. After all, with its thumping house beats acting as a pied piper to club kids passing by on the sidewalk, the store would appear at first glance to be a one-stop shop for nightcrawlers: glow sticks, high-sugar candy, striking jewelry, and all the incense, posters, and tchotchkes needed to redecorate your crib the morning after. But in the midst of all these lifestyle accessories, Uncle Sam's hasn't forgotten about the actual music. Its used section remains the area's most diverse, with a steady stream of new releases coming in every week. Even better: listening stations to hear a CD before buying it. Admittedly the $7.99 price isn't quite the bargain it once was in this age of free Internet downloads and CD burners, but for those with neither the time nor the wherewithal to go digital -- or those still wedded to the old-fashioned method of browsing -- these are the overstuffed bins of choice to paw through.
