A study found that the energy of music affects our memories. Researchers looked at the memories people had after listening to music. A music psychologist said the tempo and mood of songs affected what people remembered about their past. She said high-energy music made people remember funny and happy events. However, slower and acoustic music brought back memories of calmness, sadness, and even romance.

In the study, 233 people listened to songs from their childhood. The researchers said the feelings people had about music affected their memories. They said how much a person liked a song changed what memories they had. One researcher said acoustic songs brought back memories that contained "complex emotions like romance". The research will be put into a database of musical memories and uploaded onto a website.
