I completely agree with everything ONELABEL has said
I would add this though as some food for thought...
I can even think of brilliant songs that have only broken through due to some random piece of luck
I read somewhere (I wish I could remember the full quote) something along the lines of:
In this industry "luck" is being FULLY PREPARED for any opportunities
eg. do you always have a CD (with contact details written on it), a card with links to your soundcloud, etc. etc. on you at all times
When you bump in to Simon Cowell at a service station, Pharrell in Starbucks, a record exec in McDonald's etc. etc. are you prepared to take the opportunity?
Can you increase the likelihood of these opportunities occurring? - do you know where publisher's hang out, would you recognise your dream music industry contact (which is not always the artist), do you know where these guys hang out etc. etc.
If you REALLY wanted it, and felt you have the material strong enough, you need to be doing all of this and more - most stories from successful songwriters have similar themes about upping roots and moving to Nashville, New York etc. to "pound the streets" ad build up that all important network
If you are not prepared to do this then TAXI is probably your best alternative to get your songs heard by the industry (not necessarily "picked up" but I think you would get some valuable feedback)
This will end up being expensive, but cheaper than moving cities!
A cheaper (free!) alternative is to post your songs here asking for specific feedback - eg is this song "current" enough, is it "commercial" enough, is it suitable to pitch to ####### (insert artist/band name of your choice)
