Suppose you are telling me about composers, if that is the case then I wouldn't be able to specify, but basically my favorites would be LemmyLada, GamesAreJust4fun, and Lux

They would be the main ones since I love many of their songs and I always feel that some of their songs would be perfect for some rhythm game chart

Now suppose you are telling me about artists who make art, I'm sorry, I don't have a favorite because there are too many people who make beautiful art and I never have a favorite in that ┐(￣ヮ￣)┌
