Why not just have the lyrics premade before putting them on the player. Have you tried to set lyrics for mp3? I did this for a party and it was not fun. After find the lyrics on a website I had to sit there and press spacebar while listening to the song to set where it scrolls to the next line. Believe me, I would love to have a lyrics scroller for people to sing along to (actually this is my second thing im dying to have on my empeg, 1st is gps) I wouldnt want to have to edit them in the car. Plus opening up a way to screw up my filesystem while driving make me shutter... ; )
Just out of curiosity, hows the lyrics project comming along? If you need some help let me know. Or if you want someone to test things out i glady will. I think if anything is created for public someone could setup a webpage to post and download lyrics for songs with preset scrolls in them.
