How to improve the sales of works

Thanks, Talekeeper_Music - I understand what you are saying and it makes sense.
But...
When customers are listening to a song on here, they hear the finished product and really have no idea how long it took to compose. This may be naïve, but I would suppose that the quality of the music would play into their decision of which song to buy.
But...
If the number of tracks you have on here plays into the likelihood of your song being heard (and bought) then it seems we are painted into a corner where there's no joy in creating and posting songs. I guess I have a lot to learn :)
