One for the real pilots here rather than for those of us that merely play on a sim :-)
For those of you that fly commercially (or otherwise I suppose), are you allowed to have any kind of background music while you fly? Especially if you’re on a long haul. I know you’ll have plenty to do and need to keep distractions to a minimum but I always wondered whether you had the capability to plug in an MP3 player :-)
If so, what tunes do you blast up there in the cockpit?
