Zia is a dinosaur, but a soft and cuddly one. Now that Tower Records is petrified, this is the only music store where you can actually shop at and touch and feel an album before you buy it. I like that it's open til midnight EVERY night, so if the whim strikes you, hit the place up. The employees are friendly and helpful, and the real value is in the older albums of less mainstream musicians you happen to like. For example, I just picked up Joe Satriani's Crystal Planet electric guitar extravaganza for $7. The guy owns the fretboard.
Also a lot of deals on certain DVDs, I think they have a 3 for $10 bin.
The visual aspect of going some place and choosing your media is the real draw. It's just fun.
