Westlife is an Irish pop vocal group formed in 1998 that dominated early 2000s charts with polished ballads like Flying Without Wings and You Raise Me Up. The exact track and source of this short upload are unclear, so it is best treated as an anonymous fan clip rather than a documented recording. It circulates on soundboards as a comedy reaction sound, where the band's earnest style becomes the joke. Meme creators keep reaching for it because the contrast between sincere pop and silly edits never gets old.
