Yes of course ,thats the first thing..doing something that even the top recognized writers only pull of now and again..
2nd, someone of importance as to get to hear it, and if they care or can be bothered they might give it more than a thought,because they already have a collection of writer friends,that usually produce what they want for the artist they look after..so on and so on..
Being negative i know...but the stand alone songwriter as our friend Ralph calls them , is really up against it with out a track record of work and friends that count.
One thing i have read several times though is , find an artist whos up and coming and write for them , so if they become a star , you will be in their circle and then your songs may be hits.
