I enjoy music much more if I'm playing computer games at the same time. I think it's because I over concentrate on music if I listen to it by itself, I become too analytical and can't just sit back, relax and enjoy.
Old shoot-em ups such as Doom or Quake work particularly well, as does Pro Evo and Timesplitters 3.

Anyway I was wondering if you people like playing games whilst listening to music and if so what do you play?
