Did this Song really do 180 Million Dollars of Damage to United Airlines?

This man's guitar was destroyed by the airline's baggage handlers during a flight last year. United Airlines refused to pay him for it, so he wrote this song called "United Breaks Guitars," and published it on YouTube, where it was watched over 4 million times.

Chris Ayres of The Times Online in the U.K says that the song cost United $180 million,by causing the stock price to fall 10 per cent. (Which would have been enough to buy more than 51,000 guitars like the one they destroyed.)
