One example of a song that might make some people feel sad even though it's not inherently a sad song is "Mad World" by Tears for Fears.
"Mad World" was originally released in 1982, and while it has a hauntingly beautiful melody, its lyrics portray feelings of alienation and disillusionment, which can resonate with listeners on a deeper emotional level, leading to a sense of sadness or introspection.
Additionally, individual experiences and personal associations with certain songs can also influence how they are perceived emotionally. A song that holds specific memories or connections to someone's past might evoke sadness for them, even if the song itself is not inherently sad.
Remember, emotional responses to music can vary widely from person to person, and what one person finds sad, another may not. Music is a powerful art form that can trigger a broad range of emotions based on personal experiences and perceptions.
