I have worked the xmas season in both Macy's and Joanns... both play constant xmas music for the entire two weeks leading up the xmas and then at least weeks after. All i can say is that they ALL get annoying after a while. Hearing the same song 5 times a day even tho they are by different artists every time will sure make you sick after an 8 hour day.
One that I hear often at work is "I want a Hippopatumus for Christmas..." AAAAAAAAAAGGGGGGHHHHHH!
And then "All I want for Christmas is my Two Front Teeth"
"I'm Getting Nothing for Xmas..."
Just to name a few...
