Zen City Records Closing?

A few weeks ago, just before being incapacited by illness and derailed by death, I was motoring past Zen City Records on Valencia Street in a friend's car and noticed a big "For Lease" sign up in their window. Could this be the end of another San Francisco DJ vinyl shop? While I mentioned in a previous post that I never bought records there because all they stock is house, and another record store proprietor told me he didn't know how they stayed in business, it's still disheartening to see another record store disappear. Are they being driven out by online shops, or is everyone just switching to CDs these days? Or perhaps there just isn't the demand for DJ tracks in general that there once was. If that's the case, it's a sad sign for the SF scene.
