U2’s “One” may seem like a song celebrating unity, but it was born during a turbulent period for the band. Bono, the lead singer, explained that the song reflects not the idea of everyone living together but the recognition of differences. It’s a bit punk rock and anti-romantic.

The lyrics say, “We are one but not the same; we get to carry each other.” It’s about helping each other, even if it’s not always romantic. Surprisingly, many people choose it for their weddings, but Bono finds that a bit odd since the song is more about separation.
