Do the majors have "Staff Re-Mastering engineers? Are they chosen on skills that are commensurate with the project at hand or just who happens to be around? Does the recording artist have any input as to who the choice should be? Are there recognized re-mastering experts for different kinds of music? Would a re-mastering engineer decline a project because he/she might not be comfortable with the type of music? Does anyone have any factual answers to the above questions?
