"Some Days Are Diamonds" is a song written and originally recorded by American singer-songwriter and musician John Denver. The song was released in 1981 as the title track of Denver's album of the same name. The lyrics of the song portray the emotional ups and downs of life, acknowledging that not every day is perfect. It suggests that life is a mix of good and bad days, just like how some days are diamonds (representing the moments of joy, success, and fulfillment) while some days are stone (representing the challenging and difficult times). The song reflects on the struggle to maintain a positive outlook and to cope with the hardships that life presents. Denver acknowledges that when people ask how he has been without someone, he often responds with a simple and optimistic answer, saying that he's been fine. However, the truth is that it's not always easy to put on a brave face and pretend everything is fine. Denver admits that telling the truth about his feelings and experiences would reveal a different story. The song acknowledges the struggle of trying to maintain a positive facade while dealing with the reality of difficult times. As the song progresses, Denver reflects on the changes he sees in himself. The face he sees in the mirror is becoming increasingly unfamiliar, and he recognizes the danger of becoming someone he never thought he would be. This could be interpreted as a reflection on personal growth or the fear of losing oneself in the face of adversity. Overall, the song conveys the universal message that life is a combination of both good and bad days. It encourages listeners to acknowledge and accept the challenges they face while appreciating the moments of joy and clarity that come along the way.
