Which music do you like to hear whilst playing chess?

Music, I believe helps me concentrate on my games and allows me to focus on my chess getting rid of all distractions on my mind (and hopefully winning my games, fingers crossed!). The question is though, which music is most effective. Personally I firmly believe that it is definitely classical; although 'Pop' is sometimes more appreciated in my case.
