Since wondergirls appeared on most of them i think this is quite useful for you 😀
The following are information that I have researched about the four major music shows in Korea right now. All the times stated are Korean Standard Time, so please check your timezone. Shows are sometimes pre-empted or cancelled due to live broadcast of generic sports event or otherwise. Please check at their specific Soompi threads on the day itself to see if it’s showing.
M! Countdown is shown every Thursday via MNET from 7 – 8pm. It’s currently hosted by Chae Yeon and Alex. Every week, two singers/groups are picked to vie for No.1. Winner is announced at the end of the show. How they calculate the scores are pretty vague but usually the most popular ones will win. Not verified, but it seems like you can win for a maximum of 3 times.
Music Bank is shown Every Friday via KBS2TV from 6.30 – 7.40pm. It’s currently hosted by Yoo Se Yun and Seo In Young. Music Bank determines their No.1 weekly through their K-Chart ranking system by adding and ranking through album charts (20%), digital music charts (50%), and audience rating (30%).At the start of the show, the hosts will announce the top 3 and the winner will be revealed at the end of the show. There are currently no known limits on the number of times you can win K-Chart. Jewelry holds the record for six consecutive No.1 on K-Chart with One More Time in March and April.
