"Beautiful Day" is a song by the rock band U2. It is the first track from their 2000 album, All That You Can't Leave Behind, and it was released as the album's lead single. It was a commercial success, helping launch the album to multi-platinum status, and is one of U2's biggest hits to date. Like many tracks from All That You Can't Leave Behind, "Beautiful Day" harkens back to the group's past sound. The tone of The Edge's guitar was a subject of debate amongst the band members, as they disagreed on whether he should use a sound similar to that from their early career in the 1980s.
