aespa just got an All-Kill. What is that?

For those new to K-pop culture, you may have seen that aespa’s “Supernova” recently achieved an “All-Kill.” It definitely sounds cool… but what does it mean?

 

Put simply, an All-Kill is when an album or a single hits #1 across all major South Korean music charts. A Perfect All-Kill is when you take all charts simultaneously. In the case of aespa, “Supernova” achieved a Perfect All-Kill.
