Foobar is free and will do this.
Just load the songs in question into Foobar playlist, highlight the songs, right click. Click "properties" which will give you a box where you can select (title, song, etc) then click "edit."
After you're done changing info, make sure to press "update info," then "reload info from file." By then, the song display in Foobar will have changed to new edited format.
