Thanks everybody! It's really helpful, for me, to read your kind suggestions.
Just wanted to clarify that I'm not looking to make a living out of it. What I would dearly love is for a couple of my songs, at least, to be properly recorded (i.e. by an artist with a better voice than mine) ... and then, of course, if there are ways of getting them to a wider audience (i.e. not just personal friends and family), that would of course be great. But no more than this.
David Cuny: you make a point about a song having to be commercial to succeed. To an extent, I take your point; but there has, in my view, to be a balance. That is to say: yes, a song can't be so personal that it's unsellable; but I'm not interested in writing the latest pop craze, either, with no personal meaning attached. I do believe that audiences love "deeper" songs, too - despite what those who feed us cultural garbage would like us to think. So yes, I see your point, and it's good to write things that people can relate to (and will therefore buy); but I'm not going to go any further than that, in my writing, even if it means it goes nowhere :-) Just to clarify, that's all - but thank you for your kind and genuine thoughts on this, it's good to know where I stand on things, vis-a-vis the recording industry!
Everyone: I've been off, taking care of a sick relative, for a while. So many of you have given me amazing advice - I will try to reply to, and thank, each one of you in due course. For now, know I read it all and appreciate every word - thank you.
