Request for a music course

when I go to select music under arts/humanities it doesn't have a course for hit but when I go to search it, it does. when will you add a music course for elementary to high school level students? the federal law now states that music is considered a core subject. The states have the choice to choose if they want to apply it. Please help us out with a music course so that the ones that are users can set Goals and check the class progress.
