So you asked how to have scrolling lyrics.

1. First and foremost you need to have an Android device to enable it.
2. Start by uploading your music to the Smule site. Use the Android option as this feature is not enabled for Apple devices yet.
3. Once you've uploaded your music, you will be prompted to enter the title, and the artwork, and tags for finding the music which I usually put down as the song title an artist.
4. Sure you add the option to include lyrics.
5. Click next and then here is where you can either paste in the lyrics or type them out with a maximum of 40 characters per line
6. After you've entered the lyrics, click next and this is where you have to time how they'll scroll. You will have the option to hit space to go to the next line or backspace to go back and edit the previous line
7. The song will play and simply press space to go to the next line if you miscalculate you could either edit or hit backspace to do it over again.
8. I noticed that it does not intuitively highlight the line that you were on, but rather the previous line is active if that makes any sense. If you do it once you'll understand.
9. When you've completed the whole song with all the lyrics click next and you'll have the option to review and save.
10. Once it it's saved You must use your android device to interest me at all and go to the community pages to find your song
11. When you find your song selective and choose duet at this point you can add your vocals as you normally would. When complete click save and you're all done!
That's it...good luck!😃👍
