@Rightly - man, your vox are PERFECT for your songs, very distinctive and full of emotion, they are sometimes, not often, a little out of tune, which is easily fixed..
Maybe some listeners are fine with it, but i just say as i hear...your songs wouldn’t be the same giving the vocals to others.. Which famous artist would you want to sing for you?
Bowie, Cohen, Stormzy, Sheeren? Wouldn’t be the same man...
