That's surely worthy of more serious scientific study. It definitely wouldn't surprise me to see a strong correlation between code quality/ correctness and background distractions (not just audio) at the time of it being written. Or at least between the rate of correct code output and level of distraction. Personally I very rarely find any benefit to having music playing while coding, unless it's to block out other sounds I can't avoid. Whatever increase in immediate enjoyment there might be would be quickly canceled out by the realization I'm not focused 100% on the task at hand and making silly mistakes/taking too long over it.
