music a level

i’ve heard a lot of negative comments about music a level and am just wondering if it would be a good choice! currently thinking maths, english lit, biology and then music as well as an A level and then potentially dropping to AS. I want to be a freelance percussionist and music teacher at a school when i’m older however I’m not sure if i 100% love academic music as i think i prefer the performing side of it to be honest. any opinions would be helpful - i am currently on track for a 9 and the exam board for a level would be AQA! I think i want to do music further however i have no real idea what i want to do and want to keep as many options open as possible - from my other a level options you can probably see! any tips for what a levels for an all rounder to keep options open would be much appreciated as well
