We love Good Records, with its yellow racks with colored light bulbs, in-store performances, magazine selection and barbecues, and we shop there a lot. But we're cheap bastards, and CD World appeals to this side of us. There are rows and rows of new and used--from Turbonegro to Justin Timberlake--and all the local music that's fit to print (and sometimes not) with cheap prices all around. Also, CD World is more likely to have something for those gotta-hear-it-now moments, and the knowledgeable staff will be happy--all right, maybe a little surly--to special-order it if you think the fever will stick. But don't expect live music, unless you count that guy who's singing along at one of the listening stations.
