Know the tune but not the lyrics? Try humming it into song search.

Searching for ‘that song with the da-da-da bit’ is a lousy way to spend a break. If you can remember the tune, you can give the phone that instead. Google's current Android help gives this route: open the Google app, tap the microphone in the search bar, choose ‘Search a song,’ then hum, whistle or sing the melody. You don't need the original recording playing nearby. This is an existing feature, not a new release. Google's 2020 research explainer describes a machine-learning system that matches hummed melodies to recorded songs, allowing for differences such as pitch and tempo. That explains why a rough rendition can be useful; it doesn't promise a match for every half-remembered tune. I'd try the bit I actually remember, then listen to the suggested tracks. A wrong suggestion might still be a decent song, but it hasn't solved the mystery. If nothing fits, save a quick voice memo while the melody is fresh rather than spend the whole break searching. I like this kind of AI help: you already have the clue, and the tool lets you use it without translating it into words first.
