The energy of music affects our memories. A researcher said the tempo and mood of songs affected what people remembered. She said high-energy music made people remember funny and happy things. However, slower and acoustic music brought back memories of calmness, sadness, and romance.

In the study, 233 people listened to songs from their childhood. The feelings people had about the songs affected their memories. How much a person liked a song changed the memories they had. Acoustic songs brought back emotional memories. The research will be put onto an online database of musical memories.
