Amazingly Las Vegas still has a few record stores where you can browse racks of cd's just don't mention iTunes when you are there. The best in town is most likely Zia Record Exchange on West Sahara which has a large selection of used and new cd's as well as dvds with a knowledgeable and friendly staff. This store often has live performances and signings as well as a large selection with good prices.
