In a perfect world, record stores and video shops would have their products grouped together by similarity (like the Pandora online "radio station"). Half the time, I find myself cruising the sections based on where I think someone might have put what I'm looking for, only to discover it was in someplace nonsensical. Where does Eliza Carthy go in the record store? Is it Pop/Rock (after all, she's done albums that sound like dance music) or Folk? Actually, in this case, the answer is that you don't find her in (American) record stores. But my point stands! Maybe if the stores were simply alphabetical by artist, with a "sounds like" directory you could consult? I don't know. This is why I get most of my CDs from Amazon and rent virtually all my movies from Netflix (just got Genghis Blues, by the way, though I haven't watched it yet).
