The CD of Einaudi helps me to concentrate inexplicably. I fully on NDR1 and his music mix, but I hear Einaudi with headphones and MP3 player no longer my thoughts as usual now and I am fully in the matter. Ergo, for me the right music to concentrate and not to do the work 2 x. I can CD only recommend because it's good for me and for you? Try it out for yourself.
