So who are the real summer queens? as of now

Imma need Brave Girls to rise from the dead and officially claim that title

Quote from Dreamer95

Queendom wasn't a summer song. Power Up is the fastest fall for an idol song that I've ever seen.

If you disqualify Queendom because it isn't Summer song to you, then let's disqualify Nayeon's Pop because it isn't a TWICE song but a song of an individual member. And dismissing Power Up is ridiculous, since Power Up peaked higher, stayed longer in the Top 10 and had overall better longevity than most of the TWICE titles you tagged as a reason to call TWICE 'Summer Queen'.

But this whole discussion is moot and trivial: no other group came close to Sistar who had ALL of their songs released in Summer chart at #1.

The group that came closest, purely based on song charting, so far is Blackpink.

No one even close to take the title from Sistar
