Perfect all-kill (Korean: 퍼펙트 올킬; abbreviated as PAK) is a music chart achievement in South Korea where a song simultaneously places at number one on the real-time, daily, and weekly components of iChart, a chart ranking aggregator of all major South Korean music streaming services operated by the South Korean web entertainment publisher Instiz Corporation, the operator of the Instiz web forum.[1][2]
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.[3] Although Instiz iChart was launched in March 2010, it does not list 2010 records. The artist that holds the record for the highest number of songs to achieve a PAK is IU with 22 songs.[4] The song with the most hourly PAKs is "Golden" by Ejae, Audrey Nuna, and Rei Ami as the group Huntrix with 1,484 PAKs. "Good Goodbye" by Hwasa holds the record for a solo act with 750 PAKs.[5]
iChart
The Instiz iChart is the first and only South Korean online music chart that aggregates the rankings of all major music streaming services in South Korea,[1] including Melon, Genie, Bugs!, Vibe, Flo, and YouTube Music which provide real-time, daily, and weekly data. The iChart has its own real-time and weekly rankings based on points given to songs. The iChart is considered transparent as it calculates scores based on various agencies' ranking data, and updates its real-time and daily charts accordingly. 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]
History
Before 2015, the iChart aggregated scores from ten music service providers; these ten agencies were Melon, Mnet, Bugs!, Olleh, Soribada, Genie, Naver, Daum, Cyworld, and Monkey3. In February 2017, major domestic music distributors such as Melon, Bugs Genie, Mnet, Soribada, Naver Music, and Monkey3 changed their streaming calculation to real-time graphics only between 12pm and 6pm.[6] This meant that anything that was released outside of this time period would not count towards the chart until 1pm the following day. This major change was reported as a measure in music chart searches largely reflecting a song's popularity.[7][8] In May 2017, Olleh and Monkey3 were excluded from the Instiz iChart ranking calculation and Naver Music's score doubled. In February 2019, Flo was added to iChart. In October 2019, Mnet discontinued its service and merged with Genie, and was later removed from the chart. 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.[9] Streams and downloads from the last 24 hours were calculated instead of the last hour.[10]
Mechanic
The iChart gathers the data and attributes points to each song.[11] The Instiz iChart attributes bonus points for more popular and widely used platforms than others.[citation needed] It applies a multiplier to the accumulated points that a song gets from certain charts. This multiplier only applies on daily charts.[12] The following table shows the maximum points for every chart.
| Streaming service |
Multiplier | Points | Description |
|---|---|---|---|
| Melon | 6x | 12,480 | the largest of the major digital music providers in South Korea, which has a market share of around 40% online subscribers.[13] It provides real-time (24Hits) and daily (Daily Top 100) rankings. Its criteria are 40% streaming (for accounts verified by Korean phone number) and 60% downloads for the past 24 hours.[14] |
| Genie | 4x | 9,120 | a subsidiary of KT Corporation, is the 2nd largest music service provider in South Korea and has 24% market share. It provides real-time (Top 100 Realtime) and daily (Top 100 Daily) rankings. Its chart calculation is based on 50% streaming and 50% downloads. Genie chart freezes from 1 AM KST until 7 AM KST daily but the streams are still counted during this period.[15] |
| Vibe | 2x | 3,360 | created by Naver in partnership with YG, and accounts for 10% market share.[citation needed] It provides real-time (Today Top 100) chart data. |
| Flo | No daily chart | 5,040 | a relatively new service provider that was created by SK Telecom in partnership with JYP, SM, and Big Hit. It accounts for 18% market share. It provides real-time data only.[16] |
| YouTube Music | Weekly chart only | 5,040 | developed by YouTube and held the third-largest market share in Korea (19.22%).[17] It provides weekly data only.[18] |
| Bugs! | 1x | 4,080 | a Korean digital music streaming service and accounts for 5% market share. It provides real-time (Song Chart Realtime) and daily (Song Chart Daily) rankings. Similar to Genie, its chart also freezes from 1 AM KST until 7 AM KST. |

RAK is achieved when a song becomes number one on all iChart real-time charts while CAK is achieved when a song becomes number one on all iChart real-time and daily charts. For a song to achieve a PAK, it needs to become number one on iChart weekly chart as well.[19]
