If you REALLY must have lyrics you have a few options as of now.
EASY…. Take a screen shot of the lyrics, load an mp3 and then navigate to your picture.
NOT AS EASY…. make the mp3 an avi and include a .srt subtitle file (this is possible but I wont explain it further, sorry)
hmm, you could also go on youtube, find a song with lyrics on screen and use one of the many youtube FF plugins or other tools to grab the flash 🙂
