I used to work at a major outdoors retailer. The music on blast wasn't too bad most of the year because they actually had like a 12-hour playlist, so nothing repeated.
Then Christmas arrived. There were still no repeat tracks throughout the day. But the thing about Christmas songs is that there's only like 10 songs that have each been recorded by like 15 different artists, so while the individual recordings didn't repeat, we'd still hear the same song 8 times a shift.
Americans are fucking amateurs. In Japan (they also have stores in Hawaii and Guam) there is a retailer called Don Quixote (it’s like upscale Japanese Target). They play one song and ONE SONG ONLY on repeat during all business hours. 365 days a year.
Nobody know. She just appear one month and disappear for the rest of the year. Though someone suggest she's actually Christmas Spirit, and Santa Claus is the one seal her in ice every year.
