Any way to add scrolling text within a Prezi?

I am a teacher having students look at songs from various 20th Century Conflicts and I would like them to post the lyrics to the songs in addition to the actual MP3.  However, if I copy and paste the lyrics into a Prezi, the length of the lyrics makes the text appear huge!  I would love to be able to have the ability to let a user either scroll down on the text or if the lyrics could automatically scroll like the end credits of a movie.
