Most songs with vocals have lyrics available on Artlist. For every song that has lead vocals, you'll see a small microphone icon to the right of the song title. Click to view the lyrics and if they're available, a popup will appear.
They can also be found in two other locations on the site:
Visit the song page and select Lyrics in the options found under the song title. If lyrics are unavailable, this option will not appear on the song page.
Use the search bar to type in a key word or line from the song and the options will populate.
