Got a problem! Please sb help!

My ipod的, ipod has been 展示 different 图标 on the wrong songs! Now, I know that if I had a version of Itunes before 8.0 I could just press disable and then press enable 图标 so that it unblocks. Thing is, I have the 10.0 version and that selection has been removed.... Does anyone know any other way which wont mess up my songs?

Thank you.
