The "music" is just a bunch of commercials from the 40's-60's. The only real song in there is "Gienn Miller - In The Mood".
Use the arrowkeys to steer the plane and "m" to mute the radio. The bombs you drop will have the same speed as the plane had when the bomb was dropped. So, fast plane equals to fast bombs and slow plane equals to slow bombs. Easy :)
