What do you know about the Music Publishers ?

It is often said that music publishing is a least known segment of the music industry in understanding.

It is like this. When ever any artist comes up with the hit song what will get him or her sign to the major record label.
And then in one year time the record company is anticipating a release of new album of equal or better in hits standing.

Sad to say but Muses are some times stingy when it wilothingl come to writing hit after hit. And so artists manager have to turn to the music publishers for help.

Many songwriters feel offended by the prospect of sharing the royalty with the music publisher.
Cliff Jones did explain this situation on my seminar like this. If you write a hit song it is 100 % yours.
But your hit song is bringing you 100 % of nothing.
However when you will sign your song with the music publisher who will ask you for 50 % of your song.
Then you will have a 50 % of something. And what is better 100 % of nothing or 50 % of something ?
