Welcome to the Official Popjustice K-Chart thread! Here you will find Popjustice's K-Chart, published weekly in Top 40 format. The information presented here is compiled using data from K-Pop fans right here on Popjustice, including streaming and requests. The weekly chart and chart methodology can both be found below. If you'd like to have your data included in our charts, please join Popjustice today and get started! Is here! Join us. Let us harvest your data. Acceptance to the group is moderated, which keeps it to just those of us on Popjustice, and specifically those of us on Popjustice who are K-Pop fans. HOW TO JOIN THE GROUP Click the "join group" button at the top of the page and your request will get sent to me. Please do keep in mind though that this is a K-Pop chart, and while I won't put an exact threshold on it, you should listen to a significant amount of K-Pop. Liking just one K-Pop artist or song is not sufficient. (Feel free to criticize the methodology~) The chart is a combination of 3 distinct components: PLAYS Simple enough to understand. The plays each week in our last.fm group make up the core of this chart. Last.fm is the easiest way to measure what people on Popjustice are actually listening to, as it takes into account streams from iTunes / iPod, Spotify and Youtube. As with all last.fm group charts, plays are based on the amount of different users listening to a particular song, not the actual playcounts from each user (so for example, Person 1 could have played "Song A" 100 times in the last week, but it only counts as 1 play in the group chart). REQUESTS Don't have a last.fm account? Not a problem! You can also make your voice heard by requesting your favorite songs each week in this thread (or alternately by PM, if you wish). You may request up to 25 different songs per week. Each request is given the same chart value (as will be explained below), so it doesn't matter what order you put them in, though certainly rank them if it pleases you. DISCUSSION The final aspect of the chart measures how much of a hot issue *HyunA rap break* each song is within the forum. This is based on the amount of times a particular act is mentioned - either positively or negatively - in the General K-Pop discussion thread during the last week. The more people that are talking about a particular act, the higher a song's discussion score is. Similar to last.fm plays, points are awarded based on the amount of different people who have made a post about a particular act in the last week, NOT the amount of times they're mentioned overall. (Not my strongest subject, so please, feel free to correct any errors you may see!) All of the above factors are broken down as so: Plays account for 50% of the final score Requests account for 40% of the final score Discussion accounts for 10% of the final score. So for example, 21 people in the last.fm group have played "Song A" in 1 week. That equates to 21 play points for that song. 6 people request "Song A" in 1 week. That equates to 6 request points for that song. 8 people have mentioned the song or artist in a post in the K-Pop discussion thread in the last week. That equates to 8 discussion points. 21 play points x .50 = 10.5 play points adjusted 6 request points x .40 = 2.4 request points adjusted 8 discussion Points x .10 = 0.8 discussion Points adjusted 10.5 play points + 2.4 request points + .8 discussion Points = 13.7 chart points total. IN CASES OF A TIE -The newer song is always given the advantage in cases of a tie, as it helps keep the charts fresher. If both songs have been on the chart for the same amount of time then the biggest gain / smallest drop gets the advantage. If both songs are debuting and have the same amount of chart points then the song with the higher last.fm score gets the advantage. If there's a tie again then only request points are accounted for. If request points are also the same then only discussion points are accounted for. If all of these are the same then the most recently released song gets the advantage. If that's the same then the song with a physical release gets the advantage. And if that's the damn same then we give up and call it a draw, though hopefully this will never ever happen (nor do I expect it to). CAN YOU REQUEST AND BE A PART OF THE LAST.FM GROUP? Of course! Feel free to show extra support for your favorite songs each week by requesting. Likewise, you don't have to be a part of the last.fm group to request, meaning anyone from the general PJ population is free to chip in with their opinions. IS THERE A RECURRENT RULE? Songs older than 30 weeks and lower than a position of #30 will officially become recurrent and will be removed from the chart. A song older than 30 weeks can only re-enter at a position of #30 or higher. Songs older than 30 weeks which have been off the chart for longer than 5 weeks are officially "retired" and are no longer eligible to re-enter the chart. WILL THERE BE SUBCHARTS? Something I'm definitely considering in the future but for now I'd just like to get the main chart up and running. B-SIDES AND ALBUM TRACKS Are all allowed to chart, but only request and discussion scores count towards the chart. Last.fm plays are not accounted for as it's not uncommon for an act to have an entire album of songs with large playcounts in a single week (especially if it's a new release), and so this measure makes sure it isn't too easy for any one artist to dominate the chart. REMIXES Remixes are counted towards the original song's chart score, although in rare circumstances a remix may chart on its own if a) the remix is more popular than the original recording, and b) is significantly different from the original recording, as determined at my discretion TAGGED DIFFERENTLY ON LAST.FM Occasionally there are songs or artists that can be tagged numerous ways on last.fm, and this is a case especially relevant for K-Pop. For example, on last.fm SISTAR can be tagged either in English as "SISTAR", or in Hangul as "씨스타". In cases where artists or songs have multiple tags, their plays are always combined. LANGUAGE VERSIONS Language makes no difference on this chart. If it was released by a Korean artist then it's fair game. In cases of new language versions of previously released songs (such as Japanese or English versions), the new version's points are simply rolled in with the original version's chart score. INTERNATIONAL ARTISTS As K-Pop continues to become more and more global, it is increasingly common that K-Pop acts are working with international artists. While non-Koreans are not allowed to chart on their own, songs by non-Korean acts featuring Korean artists are allowed to. DEMOS / LEAKS An occurrence we rarely if ever deal with in K-Pop, but as a general rule demos are not allowed to chart if an official version is not released. If a demo leaks after a song is officially released then it may count towards the official version's chart points. FREE DOWNLOADS This is a fan-made chart after all, so free downloads, mixtapes, or "gift songs" are allowed to chart, so long as they are officially released by the artist, label or (in the cases of certain CM's) company providing the song. INSTRUMENTALS Are counted towards the original song's chart score. If the piece of music itself is an instrumental, then it counts as its own chart entry.
