Some people have spoken about getting a pro critique before getting a demo done. Well that is all good and well. However regardless of reason why you are demoing a song I fail to see a need for a paid critique. If you are demoing it for own amusememnt and not to pitch then what does it matter if you get a critique or not. If you are doing it to pitch then you should have done your homework and produced a song to spec knowing exactly what is required and a pro critique is not needed. Either way I see little or no benefit in getting a pro critique. Terry summed it up..... if you are a time served bricklayer do you really need to pay another bricklayer to appraise your work.
