Re: Grading 

"Would it be OK for me to copyedit your song pages first, or suggest the changes (having me do it and then grade each would be quicker) and then place what class they are in?" - Sure!!! If you can spare the time, I certainly wouldn't mind you doing the required edits. Its not as if anyone owns the article, you dont have to ask!

"about how you say things like, "It was released on November 10, 11, 12, and 13, depending on the region." (Yes not quoting you, just giving gist of what they say in the beginning as an example here.) I think it would be best to reword sentences like that. Maybe say "It was released on five separate dates, from November 10 - November 13, depending upon the area targeted for distribution by ______." (whatever the record label is, I dunno). How do you feel about that? Or the same sentence ending with "depending on the region", or "depending on the area"" - that makes much sense!!! I'll work on that, i'll do that bit, i'll make a small release history box in each article, and let you know when the article's ready. Then you can do a quick copy edit and grade them. Done?
