will a mix of 2 songs be good if one is in f or g major and the other one is in a minor. because both are one thing away on the circle of 5ths to c major, and a minor uses the exact same notes as c major
it's like mixing colors. i can't think of any rule exccept to try it. does orange go with dark orange? i'm sure there's plenty of ways for that to be good or bad
