逛街聽到商場在播自己喜歡的舊歌，總會覺得特別好聽，但播到新歌就沒有這種感覺。難道舊歌真的特別耐聽，才令我們更愛聽舊歌？
舊歌刺激大腦釋放化學物質 越聽越開心
當我們聽到喜歡的歌，大腦就會受刺激而釋出催乳素、多巴胺、催產素和血清素等化學物質，這些化學物質水平越高，就會越覺得舒服和開心。而且有研究顯示，聽舊歌時會激活大腦負責情緒的區域，讓人有好心情，尤其是那首歌能觸發某段印象深刻的記憶時，心情就越好。
青少年時期荷爾蒙多 情緒波動大
有調查發現，人過了30歲往往不會再聽新的歌手和歌曲，是因為長大後不愛聽新歌嗎？其實大腦在我們12到22歲之間，會分泌更多荷爾蒙，情緒波動也更大，更可能永遠記得當時喜歡的歌，但長大後聽歌不會再出現如此強烈的情緒，並非長大後不愛聽新歌。
