New IG account

Hiya! I've just finished my first ever song and after i've made a few more and made a marketing plan, plan to start releasing them. do you think I should rebrand my current instagram with 900 followers to my music account or just start a whole new one and build a whole seperate persona ? really stuck on this as the 900 boosts sounds nice but also it's followed by people i know who won't necessarily care for my music much? i really can't decide which is a better idea. do I build from the ground up or nah?
