There used to be an advert for a chocolate biscuit in the UK a few years ago. A band were doing an audition for an agent. His comment ?
" You sound dreadful & have absolutely no talent. You're going to go far "
Funny but sadly true.

A lot depends on good marketing as Lawrie quite rightly pointed out. I've had one tune recorded by a few people because I made some effort and simply passed it around. Getting airplay goes a long long way to helping any material. Don't bother trying for mainstream radio, they'll only play major artistes. Get a song / tune into small independant radio stations, and try and go in person with it if you can.
