Updating missing Genres

I am searching for a program (paid or fee) that will update the missing genres in my iTunes library. There are are couple programs out there that purport to do this, but have miserable user ratings.



Can anyone recommend a way to do this. If necessary, I will do it manually if I have a source to look the genres up, so if you have a recommendation for a one by one lookup please pass that on.
