This chart shows which of Spotify's top 40 most streamed tracks of the year are more likely to make you press the accelerator. The higher the tempo and energy, the more dangerous the song.
Spotify data allows us to analyse songs for tempo and energy - two factors in any track that are likely to make you put your foot down while driving. Tempo is the speed of a piece of music and is measured in beats per minute (bpm). Energy is the measure of intensity - how busy, loud and noisy the song feels - and is measured on a scale from 0 to 1, with 1 being the most intense. We've analysed Spotify's top 40 most streamed songs of 2017 and assigned a score to each based on both factors.
Chartered psychologist Dr Simon Moore says, "Fast music can cause excitement and arousal that can lead people to concentrate more on the music than the road. In addition, a fast tempo can cause people to subconsciously speed up to match the beat of the song".
According to Dr Moore, the optimum tempo of a song for safe driving should mimic the human heartbeat. The safest songs for the road are within 60-100 bpm and not too extreme in energy in either direction (not too much and not too little).
