Musical at the Supermarket

I went to the supermarket today and while i was pushing my cart, i heard one of the staff singing along to the music blaring on the supermarket speakers while stacking some grocery items, while i was looking for the milk aisle, heard one customer also singing along to the the music, then i went to the cashier, and yup she was also singing...then i noticed that several people are singing along to the music. It was like a scene from some cornball pinoy musical comedy movie. What was the background music? Sarah Geronimo's revival of "A very special love".
