There should be an option to play music from a pre-selected collection that should be stored within each user's account.
That way, you can pretend that you're Doug from Iron Eagle, albeit in an older airplane, and kill bastards to the sounds of Queen and Twisted Sister... Of course, if you want to stay committed to the time period, I'm sure that some Glenn Miller will suffice.
You should be able to switch it on, and have it partially but not completely drown out the sounds of the flight--and yes, it should be partially evident through the com channel--just so that fellow pilots can make snide remarks about having accidentally tuned into a local radio station.
See?
