Hello there,

Listen, It totally depends upon you , no subject is hard or Easy it depends how you deals with it. As you have asked that you have taken , Music is the 5th subject , I think you should enjoy and and start taking interest then, you will loved that subject.

I think learning music will also help  you to attend piece of mind , according to me this is also going to be one of the best subject, So you should start taking interest in this subject . This is not that much hard .

Hope I am clear to you.

Thank you:)
