Replay is the debut single by singer Iyaz, released in 2009 and included on his album of the same name the following year. The song became a major international pop hit, reaching high chart positions in the United States and the United Kingdom and becoming a staple of late 2000s radio. Its simple, earworm chorus helped it survive long after its chart run, resurfacing in short-form videos, dance edits and nostalgic playlists where listeners instantly recognise the melody even without hearing the full track.
