File Description different to file
 

When I go to burn files onto CD's or drag onto itunes, some of the files register as different titles because the Description tag is for a different song, and Burner software seems to read tags, not titles. The Artist is the same but the song title is different. I know I could go through all the files and manually change them but sometimes even the edited description wont save.
Can I disable the description tag or "mass" clear the tags?
Help me please!!!!!!!!!!!!
