Guns N' Roses — Sweet Child O' Mine

The opening riff is probably the most recognizable in hard rock, and nearly four decades on it keeps finding new screens to play across. Songfacts notes that the track featured on the Thor: Love and Thunder soundtrack and ran through the film's marketing campaign, with director Taika Waititi citing it as a match for the movie's "crazy adventure" tone — one of the more high-profile syncs a catalog rock song has landed in recent years. On the placement side, Tunefind logs the song in multiple series, and the Step Brothers family singalong scene remains one of the more-quoted comedy uses of the song. Rolling Stone places Slash's guitar solo among the definitive moments in hard rock history — melodic enough to function as a second vocal line, which helps explain why the song travels so well outside its original context. Currently tracked across 119 country and platform charts, it is back after a brief gap in broad presence.
