Disable iPod "Now Playing" on iPad

I have set up an iPad running iOS 4.2 for an older person, but some features aren't intuitive for he. After he select a song in the iPod app, the "Now Playing:" box will appear. And he can't remember how to get back to the main page, so how to disable this function?Unfortunately, the "Now Playing" can't be disabled on the iPad.
