If you can’t remember what song a lyric comes from, check out the Music app in iOS 12. In the past, you could find tunes based on the name of a song, album, or artist, but with iOS 12, you can also search for lyrics! In the Music app, tap Search at the bottom-right corner of the screen, enter a snippet of the song’s lyrics in the Search field, and tap either Apple Music or Your Library to set the scope of your search. Finally, tap the Search button on the keyboard. To play the tune, tap it in the results.
