팬들이 댓글같은걸로 순위 적어놓으면 그걸 기준으로 차트 순위를 정하는 것 같네요.
특성상 거의 해외팬 선호도에 의한 아이돌차트가 되겠네요

두분다 확실하게는 모르시는거죠? 전 국내차트들 비율 다르게해서 참고해서 만드는걸로 알고있엇는데 정확히는몰라서;

Rules for the chart:

1. All new entries will debut at the beginning of the chart, unless they have already received points from fan votes. This is so that they don't infringe on what the fans have voted for in the previous week.

2. Each week you can rank your Top 10 K-Pop Songs in order of which songs you like the most. So rank your favorite song as #1, and one of your lesser favorites as #10.

3. The position you give them will be converted into points. A song you rank as your #1 favorite will receive 10 points, while a song that is ranked #10 will receive 1 point.

4. If your votes are not ranked from 1 to 10, I will assume that you like all of those songs equally and will award them an equal share of points. You duplicate songs in your list will be ignored.

5. All of the fan votes are totalled, and the songs are sorted from most points to least points.

Rules for voting:

1. Vote for no more than 10 songs please.

2. When a song has spent 12 weeks on the chart, it will automatically fall off in the next week.

3. A song that has been #1 for 3 weeks will suffer a penalty to its points total. This penalty grows by 5% each week it remains at #1 (15% on Week 4, 20% on Week 5, etc). The penalty will be removed when the songs base points no longer place it at #1.

4. A "GOLD SONG" is a song that has either:
- Spent at least 1 week in the Top 10.
- Been on the chart for over 8 weeks.

5. A "PLATINUM SONG" is a song that has either:
- Debuted in the Top 10.
- Spent at least 1 week in the Top 5.
- Stayed in the Top 10 for at least 3 weeks.

6. A "HOT ENTRY" is a song that has entered the chart within the Top 30.

7. A "HOT DEBUT" is a song from a debut group that's entered the chart within the Top 30.
