when you need to find the name of a song.

That said, it means a song like this must stand on the shoulders of giants: Cassiano: OndaFrom 12" (Polydor, 1977) "Onda" means "wave" so this is already a summer song by intent but that wouldn't mean much if Cassiano (a contemporary of Tim Maia) didn't pull everything together with a song that mostly feels like one long chorus but it's a hook that's so good, so easy to find yourself singing without realizing it, you don't want to hear it end.
