Ingrained in Stray Kids’ DNA is their creative agency. Bang Chan, Changbin, and HAN — known as 3racha — have written and produced the majority of the group's discography , but all nine members have had writing credits on their work, which isn't often seen from young bands in the industry. This ownership has allowed them to experiment and play with their sound, and even their videos — many of their visuals are of them singing and goofing off, filmed on GoPros (as one does when not questioning your entire existence). It’s also allowed them to showcase each member’s versatility. While many K-pop group members usually have defined roles within a group, there’s a joke within the fandom that Stray Kids sometimes feels like it has nine rappers and nine vocalists — whether it’s vocalist Lee Know dishing a scorching opening rap in “ District 9 ,” or rapper Hyunjin letting his gentle tenor shine in “ 불면증 (Insomnia) .”
