Super annoying music. No explanation what happens if multiple buttons are pressed simultaneously

if u hard to grasp the explanation, a simple explanation will be in1 to in4 will take turn to becoming VCC and while it become VCC, the rest IN will be set to LOW. And for each of it, each output would try to read the logic :)
