Help! Options :S Music or Geography?

okay, i'm 14 and therefore in year nine at school and i completed my options form months back. At the time, there was a slight problem. I wanted to do Music and German and Art, but they clashed together with the timetable bands. In the end, I wrote a letter to the orginiser, the person who makes the sets, but once it had been sent, i didn't really want to do Music anyway. Now, my options are back and they've only gone and done exactly what i wanted to do at the start, so i'm now doing History, Music and German. But i'm really not sure at all if Music is the right thing for me. My family wants me to do because i'm grade 3 and improving at drums (but that's as far as my musical knowlage goes!) I know that you shouldn't let your fanily decide for you but i still feel guilty telling them i dont like music. Please, advice would me grand.
