Captain Birdseye, if you are a professional performer then you should be professional about everything related to your business. Its your image and your pride. For £10 quid or more, we expect the real deal. That is a customer comment from me. I do not sing or play. I am one of the audience or punter as some people rudely say.
I mentioned shrink wrapping etc, etc , becuase to the person buying, they can see that a lot of care and attention has gone into producing the CD and visually is more marketable.
I agree about the music.
I get quite a few CD's as an organsier and to be honest 90% could go straight in the bin. Don't go down that route.
You must look at your customer and give them the very best you can do. It reaps benefits in the end.

The Churchfitters spring to mind. The qaulity of their Cd's including the artwork shows a lot of care and attention has gone into what they do. Take a look http://www.churchfitters.com/ediscographie.php
Their act is excellent as well. So much so, my audience demanded that I get them back again. They care about their image.

They are not the only ones, but I have used them as an example.
