Last August, a video from Pittsburgh went moderately viral when it recorded an Asian grocery in the Strip District playing Singapore's national anthem. A video from Panda Supermarket last week shows the same thing:
The simple answer, then and now, is that grocery stores use streaming Singaporean radio stations for their in-store music. In the case of Panda, it's YES 933 FM. The video from Panda was taken around 6:00 pm; YES 933 FM plays the national anthem at the start of its 6:00 am program.
