This growing chain has over a dozen locations: P.B., Miramar, Poway, El Cajon, Chula Vista, Santee, and elsewhere. The college-area shop has the most knowledgeable (and most tattooed) staffers and the best selection of everything from rock to country, hip-hop to folk, rap to soundtracks. The local-music section is fully stocked with titles they carry on consignment and listening stations are available for those who prefer to play before they pay. Most used discs run $8.95, trades are accepted, and your 13th CD is free.
