People of the Pit: help!

I will be in a 12hour transit in New York city. So I thought I might as well make the best of my time and go buy some CDs.

Now. The only problem I have is that I only know about the Virgin Megastore on times square. Any other big cd stores, that might have a more varied stock?

Thank you!
I thought you were asking what CDs you should play when you're walking around New York. Because the answer is Gershwin.
