New research has revealed that which song drivers listen to can influence how safe they are on the roads.Among the top ten safest songs to drive to are Come Away With Me by Norah Jones，I Don't Want to Miss a Thing by Aerosmith and Tiny Dancer by Elton John.Each of the songs has an optimum tempo(最佳節(jié)奏) for safe driving，imitating the human heartbeat at around 60 to 80 beats per minute.The Scientist by Coldplay and Justin Timberlake's Cry Me a River also appeared in the top 10.

The study，conducted at London Metropolitan University，also revealed the type of songs that cause motorists to drive dangerously.Unsurprisingly，music that is noisy increases a driver's heart rate，which can be deadly.Fast beats cause excitement that can lead people to concentrate more on the music than on the road and to speed up to match the beat of the song.Styles of music were also measured during the experiment and revealed differences between male and female drivers.Hip?hop made a female driver drive far more aggressively，speeding up faster than male driver.The heavy metal music caused the fastest driving among males in the group while the dance music had the same effect among women.The male and female drivers who listened to the classical music drove the most irregularly.

The experiment involved eight people driving 500 miles each using the confused.com MotorMate app，which monitored driving behaviors through GPS technology.

A．Songs that drivers prefer to listen to on their way.

B．A study made by the confused.com MotorMate app.

C．What kind of songs the drivers should choose to listen to during driving.

D．Female drivers and male drives have different responses to the same music.

A．Tiny Dancer by Elton John appeared in the top 10.

B．Usually human hearts beat at around 60 to 80 beats per minute.

C．The classical music makes most drivers drive comfortably and safely.
