This might go someway to expalining the breakdown of where the money goes from a CD
Based on this then, you are looking at around €1.50 per CD - also, the calculation is based on lower UK CD retail prices and on the author's admittedly "lowish" rate of 14%.
That considered, total to artist, in practice, could quite easily be €2.00 per unit.
Not a huge amount, but a good deal better than "less than €1"
(Would also agree with Elefantfresh's approach BTW)
