Check out OpenSongApp, it was developed for use by Worship musicians but works just as well for heathens like me.
I have been using this for about 4 years, I roll my own backing tracks in BIAB and RealBand, the resulting MP3 goes into the appropriate folder, a .txt file with lyrics and chords in another. Point one at the other and the lyrics scroll as the track plays. Like most things there's a bit of a learning curve, but it works well for me and has numerous options to enhance visibility. AFAIK it's Android only.
