Thank you for your question. I'll give you the answer I've written before, by Ctrl+c Ctrl+v Simply said, you can think of '의' as similar to 'of' in English. But you can use a much more diverse way. In a nutshell, It is used to indicate a [possession, Subject of action, object, property, function, apposition, relation, Degree, characteristic, result, etc] e.g. 나의 옷 [possession] 우리의 각오[Subject of action] 다윈의 진화론[object] 금의 무게[property] 축하의 잔치[function] 100℃의 끓는 물[apposition] etc. So, of course, you can say '한국의 음악' Have a nice day~
