Am new to Stage Traxx. I just downloaded a number of tracks from karaoke-version.com and saved them in iTunes playlist. I imported the tracks and thought the lyrics might show up as well. How do I get lyrics to show up? Do I need to download lyrics separately and import? How do I sync them with tracks that are already there? At this point it is not clear the advantage of playing these tracks in Stage Traxx versus just playing them in iTunes. Help
