Music app not show Lyrics in iPad iOS 5

Therer are about 90% lyrics of my 80GB's of music in my library. After I update my iPad 2 to iOS 5, the new GUI of Music app doesn't show lyrics anymore and always crashes. The lyrics still show on my iPhone 4 running iOS 5.That looks like a bug. How can I get back the lyrics on my iPad? Hopefully the issue will be fixed soon.
