Listen. Press when a line starts to be sung, hold while it is sung, let go when it ends. A quick tap is fine too. Three minutes of your ear makes the words light up in time for everyone.
Keyboard: hold Space while the line is sung · Backspace = undo (jumps back 3 seconds) · Left / Right = move the last tap by a tenth of a second.
Songs with ✓ are already timed; the others still need an ear. Type your name above and it goes on the song's page when your timing is used.
What happens next: a first timing of a song goes live at once, and so does a small fix to one that is already timed. Anything else waits until we have listened to it. We store the timing and the name you typed, nothing else.
