If song titles look scrambled after importing from another application
If a song’s title and information don’t appear correctly, the file was probably created using a program that stores information in a different way from iTunes. You may be able to resolve the problem by reversing the Unicode characters in the song tags.
To reverse the Unicode characters:
Right-click a song and choose Convert ID3 Tags.
Click Reverse Unicode.
To change the information back to what you had before, choose Reverse Unicode again.
