Many couples have a special song – “our song” – that reminds them of a significant event or time in their relationship, like when they first met, their wedding or when they were separated by war. 
These songs are a powerful way of reconnecting with their shared personal memories and the emotions that go with them. They are a type of shared or autobiographical memory triggered by music; they work as a “mental glue” for a couple’s shared identity.
Despite how common these songs are, there is surprisingly limited research on music-evoked autobiographical memories. There are, however, numerous anecdotal and film references to the power of “our songs” to bring people back to themselves and to reconnect with others, particularly in dementia.
The types of memories music most commonly evokes tend to build and maintain social relationships.
