Music App. In iOS 5 doesn't show Lyrics

Hello everybody. Yesterday I updated my iPad 2 with iOS 5. Now in the Music App the Lyrics don't appear anymore. I'm very disappointed and angry about that. Can anybody please tell me if it is a bug or if this was made intentionally. I hope tat this is a bug because the iOS 5 manual for the iPad (Ipad userguide for ios5 - downloaded from ibooks) shows on page 218 the following: "Display a song’s lyrics

Display the album cover by tapping the thumbnail at the top of the screen. Lyrics appear if you’ve added them to the song using the song’s Info window in iTunes." If it is a bug, when will it be fixed? If it is no bug, then I want to go back to its 4.3.5. Can anybody tell me how that would work?

Best Regards
