They seem to have everything most people would ever want in the way of LPs, DVDs and popular music. I go here for the jazz room on the third floor.
The fact that jazz and classical get their own space is REALLY NICE.
As far as selection goes, this flagship store is tops. While they don't have everything (nobody does), they do carry a lot--certainly most of the major titles from the major labels such as Blue Note. And with the 2/$25 on many of these, you will not break the bank--it is only a little more than used. (if you can the CD used).
You are left to browse and decide between titles without any stress or pressure. The sales staff I have encountered up there have been friendly and helpful. (We CD sellers/buyers are a dying breed and need to stick together!)
Highly recommended!
