How to play!
Players can either play the game while listening to the radio or by having a non-participating passenger play tunes from their phone. When checking players' responses, the phone increases accuracy. The name of the artist may be yelled out at any time while the music is playing.
You could also play this by stopping the music and getting the passengers to finish the lyrics - make sure the driver isn't in charge of stopping the music as it would distract them from the road!
