40

U2's song '40', taken from their 1983 album 'War', is a deeply spiritual track that reflects the band's Christian influences and their penchant for infusing their music with a sense of hope and redemption. The lyrics are directly inspired by Psalm 40 from the Bible, which speaks of waiting patiently for God's help, being lifted from a place of despair, and being set upon a firm foundation. The song's repetitive questioning of 'How long to sing this song?' suggests a yearning for understanding and an end to suffering, which can be interpreted as both a personal and a universal plea.

The song's structure is simple yet profound, with its repetitive chorus creating a meditative atmosphere that invites listeners to reflect on their own struggles and the search for solace. The use of biblical references gives the song a timeless quality, connecting personal trials with the collective human experience. The mention of others seeing and fearing suggests a witness to transformation, which can inspire awe and reverence, possibly leading to a change in their own lives.

U2, known for their activism and messages of social justice, often use their music to comment on political and personal issues. '40' stands out as a moment of introspection and spiritual solace amidst the more overtly political themes of the 'War' album. It serves as a reminder of the band's range and ability to connect with listeners on a deeply emotional level, transcending the boundaries of rock music to touch on universal themes of faith, hope, and the human condition.
