Yeah, you could also add commands, like the Now Playing script, or something, don't remember the correct name, that has a command to send the lyric, it could be like that, or if the user type like !lyric and it would send message after message, then you could have the right timing.
This if not the user that has the script gets curious about the lyrics, the contact types !lyric and voilá... the user would send the lyrics, line by line, to the contact
(did I explain myself right? lol)
