Perfect all-kill

South Korean music chart achievement

Perfect all-kill (Korean: 퍼펙트 올킬; abbreviated as PAK) is a music chart achievement in South Korea where a song simultaneously reaches number one on the real-time, daily, and weekly components of iChart, a music chart ranking aggregator operated by the South Korean web entertainment publisher Instiz Corporation, the operator of the Instiz [ko] web forum.[1][2]

Perfect all-kill certificate

The term "perfect all-kill" was first used when the song "Nagging" by IU featuring Seulong ranked at number 1 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 most number of songs to achieve a PAK is IU with 22 songs. The song with the most hourly PAKs is "Ditto" by NewJeans with 655 PAKs.[4] "Celebrity" by IU holds the record for a solo act with 462 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.[6] 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 10 music service providers. These 10 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.[7] 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.[8][9] 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.[10] Streams and downloads from the last 24 hours were calculated instead of the last hour.[11]

Mechanic

The iChart gathers the data and attributes points to each song.[12] The Instiz iChart attributes bonus points for more popular and widely used platforms than others. It applies a multiplier to the accumulated points that a song gets from certain charts. This multiplier only applies on daily charts.[citation needed] The following table shows the maximum points for every chart.

Other "all-kill" categories on the Instiz iChart include Real-time All-Kill (RAK) and Certified All-Kill (CAK). RAK is achieved when a song becomes number 1 on all iChart real-time charts while CAK is achieved when a song becomes number 1 on all iChart real-time and daily charts. For a song to achieve a PAK, it needs to become number 1 on iChart weekly chart as well.[19]
