Thanks for the replies.
I am painfully aware that just putting a song on the web doesn't sell a thing. It's all promo-promo-promo.
Looking around for somewhere to host/sell I found quite a few but have no perspective on their merits. If I never have to read any website legalese bumf again I'll not be saddened
Looks like the best option is sell them off the website, webbyman says can do and I have the PayPal.
Then all I have to do it promote... promote... promo...
