Well to start, the artist doesn't hear all the possible cuts, only the one the engineer presents as the final cut. Then the engineer will go through the limitations and how many samples he/she tried. (with a little sweat on the brow) Next, the manger tells the artist how great the sound is and this is just what we are looking for (crossing his/her fingers). The artist then (if interested) gives the nod. As long that music has a good beat, that they can take their clothes off to ...... it's a go. IMHO, most artist don't know much about sound mixing or care. The sound engineer should be wearing the big boy pants and present the best possible representation of the art and insists that go to market.
