Music, particularly music attached to positive associations, is stored in the part of your brain known as the hippocampus, which handles long-term memory. Listening to a specific song, like your first dance at your reception, will stimulate the hippocampus and trigger memories associated with your wedding, your partner and the early days of your romance.

Positive memory associations can strengthen your marriage throughout the years, so it could be a romantic gesture to listen to your first dance song on your anniversaries.
