Generically speaking, people are easily distracted by the human voice. Therefore anything that has no vocals should lead to less distraction and more focus. This doesn't affect ability, only focus. Personally, I go for breakbeat, old skool trance (Germanic Trance circa 1990-96), Experimental Techno.
