OK, Now Wal-Mart Has Crossed The Line

I went to our local Wal-Mart store this morning to get some supplies for my kid's science experiment. Now I know Wal-Mart is starting to set up Christmas trees and sell Christmas items- I understand that.
But do they have to play Christmas music over the loudspeakers on October 11 and when it will be about 83 degrees outside today?
I know, Bah Humbug.
