Facts, they are stubborn things...
People unfamiliar with farming underestimate the degree to which the comfort of animals is taken into account.
All of the investigative reporting on factory farming in the last several years would indicate the exact opposite of this assertion. The comfort of the animals in farms across the United States is dead-last in priority, behind profit, common sense and even the humanity of those involved.
Some dairies play music all day because they've found it has a calming effect and increases production.
Like anything, it's all about money.
Where are all these dairy farms in which they play music for the cows? Do the cows spontaneously break into dance, too?
Is a visit to the dentist really that much better because they pipe in muzak during the root canal procedure? Or can we agree it's still pretty freaking uncomfortable? Now imagine getting a root canal every day of your life, for a couple of years, until the last day, in which the dentist shows up with a blade. This may sound a little extreme, but it's probably not actually all that far off from the average factory farm animal's perspective and experience.
Bottom line, factory farming is still cruel, with or without the soundtrack.
