Make art/creative its own catagory
Art being under irl is an awful and detrimental decision that will only drive artists away from your platform. Artists help your community (emotes, layouts etc) don't hide them under IRL. A good portion of your viewers go into irl solely to troll and artists already struggle to gain a solid audience on your platform. Several artists have already left twitch for YouTube, putting art/creative under IRL is just opened the door and encouraging them to leave. Give creative it's own category, put music under it (it is art after all), problem solved. People wouldn't have to visit a help directory to find the creators category they're looking for. You're making a hard process even harder.
