What I have is my play lists set up by artists then albums under that. and at root I have a (favorite songs) play list. I started out putting lyrics in all my (favorite songs) songs. and I have now started at the top artist and going thru all the albums doing all the songs. and I just toggled them as I add the lyrics. I guess I could always just mark them but man that would take a while to unmark them once im done.
