When i work on a song i usually start with the beat. I then add some lyrics and change their melodic composition until it fits with the beat. i then do improvement, for example try singing like a girl or like a boy, see if it makes a difference. It is then time for EQ and some effects. sometimes i can tell from the first stage that i have something special (it's all about the beat in hip hop).
my question is at what stage do i publish it to make sure no one steals my copyright?
do other artists publish draft song then upload a new version when they have it?
