Remember the used-record store? The racks were made of dirty white particleboard, the signs were handwritten in red permanent marker, and the bald guy with the lip piercing behind the counter played in your cousin´s band. You could find almost anything there, usually for around $6. Music megastores and Web sites put these places out of business, and even if you can get just as good a deal buying a CD off eBay, you don´t get the music community that came part and parcel with your local punk-rocker-run music shop. And obscure titles are getting harder and harder to find in CD form.
