Just whatever's on the radio. We normally don't have any radio traffic to worry about unless it's an MVC (and even where I am, that's rare seeing as no one seems to believe in radio updates).
Meat Loaf - "Bat out of Hell", classic
Used to make paramedic students do CPR to "Ballad of the Green Berets",either on tape (told you I was old), or we all sang it, now it's "Stayin Alive"
Staying alive was mentioned earlier, so consider yourself corrected.
Also, Jumping Jack Flash - Rolling Stones http://www.youtube.com/watch?v=e9XKVTNs1g4
