Regarding the identity of the bell sound said to be included in BTS's latest Arirang

In the past, when welcoming the New Year, people called it the New Year's Eve bell sound.

I think we used to all flock together to listen to it.

It is a truly symbolic sound, and the same goes for this bell; it is a historical bell.

They say this resonance is really unique. I really liked it because it has the sound of bells in it.

I think they didn't just force it in, but wanted to capture the value of that species.
