Spotify has introduced a good feature that is especially useful for people who can only remember one line of text from a song (like the author) – not to mention the actual song name or even the artist.
The search function has been extended by Spotify for these people, because from now on you can search all lyrics automatically and get the matching song displayed as a result. Very practical. And probably also funny if you didn’t even understand this single line correctly.
You don’t need to do anything else than use the integrated search function of the Spotify App (probably already updated in the background) – everything else is automatic.
