"Techno/dance/electronica sometimes gets played, but only for short durations as these can give me a headache after an hour or so (there’s only so many thudding synthetic beats you can listen to before your brain starts to bleed a little)."How dare you sir! Thudding, synthetic beats are the only thing I can listen to for hours and the bleeding of the brain? That's an added bonus, under the right circumstances ;)
Unless of course you're referring to House music and then I agree. Two minutes, in that case, is more than enough to make my head hurt.
