I've done a lyrics program for winamp2 and winamp3. so far, it's the best lyrics program you can find over the net. It's new so it didn't published yet. you can download it from www.winamplyrics.tk
see the screenshot (and it's totaly freeware)
If you have any ideas or you want to help in the development / testing, feel free to contact me. Thank you very much and I wish you'll like the program, just give it a try!
