Warren St. John wrote with some air of complaint about oblivious iPodders who clog our streets and queues while lost in their own musical worlds. This may be annoying, true, but it's much better than the opposite situation: music that is piped into the street by retailers and/or Real Estate Experience developers. It's particularly bad on faux-urban streetscapes, like the Market Commons at Clarendon, a "retail mecca" just outside DC. Nestled among the landscaped bushes are little mushroom-shaped speakers that pump out a chain-store-friendly soundtrack all day and night. It's freakin' annoying.
