Grenade was released by Bruno Mars in 2010 as a single from his debut album Doo-Wops and Hooligans, becoming a worldwide hit built around its piano melody and dramatic chorus. The song's theme of extreme devotion made it a staple for emotional covers, talent-show performances and social-media edits long after its chart run. Extended versions circulate online because fans and creators want the full build and chorus without the short radio cut, keeping the track popular for montages, lyric videos and dramatic storytelling.
