A lot of Kpop group stick to one producer once they get successfull but it seems that it's hurting them more than helping them because once this group lost this producer or this producer lost his touch the group start "flopping " for example : Twice build their entire brand on the cute bubble pop sound that BEP created for them; BEP is the producer who gave twice their biggest hit in korea and also their last hit in Korea with fancy but since BEP is now focusing on StayC, twice can no longer use his talent and their performance in the chart in korea become worst and worst since Fancy Loona for the debut of their group career worked with Monotree and got a lot of attention and people had a lot of hope for their futur, but since So What they stopped working with Monotreee on their title track and it seems that they lost a lot of attention from kpop fans after this Sunmi career went well with JYP then she worked with Teddy for Gashina and heroine who have been very well received and since she stop working with teddy since Siren, she completely lost her popularity and just fade away in the background Chungha had a very successfull debut of career working with BEP and Oreo but the past years she stopped working with them and start working with Vincenzo and now her career is going downhill there's a lot of example of Artist working with a producer becoming really successfull and once they stop working with this producer their career in the chart seems to go downhill (there's also some artist being able to be as successfull while working with different producer, but they seem more rare, because these successfull artists usually stick to the same producer once they find the success BTS/Pdogg, BP/Teddy, Aespa/Yoo youngjin) Is it a proof that the producer is more important than the artist itself ? because you can see producer working with various artist and be able to make them really successfull like Teddy and BEP but once they start working with this artist, even if the artist is still the same, once they start to work with someone else they can't find the same success anymore Do you think working with the same producer for an extended period of time is a good idea for idols ? do you think all these idols doing badly after working with other producer, is a proof that the producer matter more than the artist itself ?
