The term "perfect all-kill" was first used when the song "Nagging" by IU featuring Seulong ranked at number one on all Korean music charts in June 2010.<ref>{{cite web|script-title=ko:2010년 24주차 Digital Chart|url=http://gaonchart.co.kr/main/section/chart/online.gaon?nationGbn=T&serviceGbn=ALL&targetTime=24&hitYear=2010&termGbn=week|work=Gaon Music Chart|language=Korean|access-date=May 4, 2021|archive-date=November 25, 2016|archive-url=https://web.archive.org/web/20161125050200/http://gaonchart.co.kr/main/section/chart/online.gaon?nationGbn=T&serviceGbn=ALL&targetTime=24&hitYear=2010&termGbn=week|url-status=live}}</ref> Although Instiz iChart was launched in March 2010, it does not list 2010 records.

"Good Goodbye" by Hwasa holds the record for a solo act with 750 PAKs.<ref name="PAK-songs"/>

==iChart== The Instiz iChart aggregates the real-time, daily, and weekly rankings of major music streaming services in South Korea,<ref name=":0" /> including Melon, Genie, Bugs!, Vibe, Flo, and YouTube Music, producing its own real-time and weekly rankings based on points given to songs. The users can also visit the source agencies' websites directly to compare rankings. The records may be accessed by the public for three months.{{citation needed|date=February 2024}}

===History=== Before 2015, the iChart aggregated scores from ten music service providers: Melon, Mnet, Bugs!, Olleh, Soribada, Genie, Naver, Daum, Cyworld, and Monkey3. In February 2017, major domestic music distributors changed their streaming calculation to real-time graphics only between 12pm and 6pm.<ref>{{Cite web |last=Park |first=Young-woong |date=February 15, 2017 |title=[단독] 음원차트 개혁, '0시 줄세우기' 사라진다 |trans-title=[Exclusive] Music chart reform, 'line up at 0 o'clock' disappears |url=https://n.news.naver.com/entertain/article/076/0003050373 |access-date=March 28, 2024 |website=Sports Chosun |language=ko |archive-date=March 28, 2024 |archive-url=https://web.archive.org/web/20240328201809/https://n.news.naver.com/entertain/article/076/0003050373 |url-status=live }}</ref> This meant that anything that was released outside of this time would not count towards the chart until 1pm the following day.<ref>{{Cite web |date=March 30, 2017 |title=IU continues to dominate Korean music charts - Entertainment |url=https://www.thejakartapost.com/life/2017/03/30/iu-continues-to-dominate-korean-music-charts.html |access-date=March 28, 2024 |website=The Jakarta Post |language=en |archive-date=May 13, 2021 |archive-url=https://web.archive.org/web/20210513035522/https://www.thejakartapost.com/life/2017/03/30/iu-continues-to-dominate-korean-music-charts.html |url-status=live }}</ref><ref>{{Cite web |last=Park |first=Soo-jeong |date=February 15, 2017 |title=[음원차트 바꾸기③]"개혁 반대" 아이돌 팬덤의 목소리 |trans-title=[Change the music chart ③] Idol fandom's voice "opposes reform" |url=https://n.news.naver.com/entertain/article/112/0002894117 |access-date=March 28, 2024 |website=Herald POP |language=ko |archive-date=March 28, 2024 |archive-url=https://web.archive.org/web/20240328201712/https://n.news.naver.com/entertain/article/112/0002894117 |url-status=live }}</ref> In May 2017, Olleh and Monkey3 were excluded from the Instiz iChart ranking calculation and Naver Music's score doubled.

Naver Music has also been removed and replaced with Naver VIBE.

In May 2020, Melon made some changes to its real-time ranking calculation. The chart changed from rankings based on hourly usage per song to a chart calculated based on the number of unique listeners.<ref>{{Cite web |last=Kim |first=Mi-ji |date=May 20, 2020 |title=지니뮤직 측 "실시간차트, 순기능 살리며 유지할 예정"[공식입장] |trans-title=Genie Music side "We plan to maintain real-time charts while maintaining their positive function" [Official statement] |url=https://n.news.naver.com/entertain/article/311/0001149057 |access-date=March 28, 2024 |website=Xports News |language=ko |archive-date=March 28, 2024 |archive-url=https://web.archive.org/web/20240328204329/https://n.news.naver.com/entertain/article/311/0001149057 |url-status=live }}</ref> Streams and downloads from the last 24 hours were calculated instead of the last hour.<ref>{{Cite web |last=Lee |first=Min-ji |date=May 19, 2020 |title=멜론, 실시간 차트 없앤다 "여름 적용 목표"(공식입장) |trans-title=Melon eliminates real-time charts "Summer application goal" (official position) |url=https://entertain.naver.com/read?oid=609&aid=0000278896 |access-date=March 28, 2024 |website=Newsis |language=ko |archive-date=March 28, 2024 |archive-url=https://web.archive.org/web/20240328204329/https://entertain.naver.com/read?oid=609&aid=0000278896 |url-status=live }}</ref>
