Need Advice: Starting social media from scratch

Hi everyone, good day to you all!

I'm seeking social media marketing/branding advice and I wondered if you could provide some helpful info on the subject.

I am a musician and I've recently considered pursuing the trade somewhat more professionally.

The social media accounts that I use (Namely SoundCloud, Twitter, YouTube etc.) have been the same ones I used when I started out just as a hobby.

I knew very little back then about how to use social media effectively, and so as a result, my accounts have grown inconsistently, i,e random and irrelevant followers/following (with low ratios) slight variations of the same handle name, irregular, inconsistent content posting etc.

To be blunt, I can only describe my social media presence as 'amateur-like'.

This simply won't cut it in today's competitive market, so my dilemma, and the ultimate question is:

Should I just restart all of my social media activities again from scratch, with a strategy this time?

Its really bugging me as I want to just start all over again, including a new email name to link them all to.

My only concern is losing some of the genuine followers I have attracted along the way, although they are few.

Does the clarity of having clean social media accounts outweigh the loss of a few followers?

I would love to know your suggestions on this issue and I look forward to your responses,

Much thanks : )
