Why do people enjoy hearing old songs?
Music does not only preserve sounds. It preserves moments.
An old song begins, and suddenly a forgotten year feels close again.
The lyrics may have faded from memory. The singer's name may take a moment to recall. Yet the emotion often returns immediately.
Music connects strongly to autobiographical memory. Songs become attached to friendships, summers, heartbreaks, and celebrations. Years later, hearing them again can recreate the emotional atmosphere of those moments.
Neuroscientists have repeatedly found that music activates brain regions associated with emotion and memory. Sounds often survive in memory differently from facts or images.
People think they listen to old songs because they like the music. Sometimes they listen because, for a few minutes, they like meeting the person they used to be.
