"New research from France finds restaurant patrons exposed to music with pro-social lyrics are more likely to leave tips." Miller-McCune on another delicious French sociology study: "After crunching the numbers, the researchers found the pro-social lyrics inspired generosity. Patrons who heard either the restaurant’s usual soundtrack or the emotionally neutral songs gave tips 24 percent of the time. Those who heard the songs with pro-social lyrics gave tips 35 percent of the time. What’s more, at the dinner hour, the size of the tips was also significantly bigger when the pro-social lyrics were on in the background. Not only did more people tip, but those who did gave more on average than patrons exposed to other types of music."
