Bravo on this comparasion once again! And yes, Looking back on it know, I also sorta wished that they scrapped the anti-fighting lines in the dub. It would have pretty hypocritical coming from a franchise that basically based on fighting creatures til they faint.
I did not know that phillip bartlett died. :( And reading your comparison was the first time that I have heard about his death. And yeah, Christina A was the few names that recognized on the paragraph of songs (and baby spice [emma bunton] from the spice girls.) they were able to get some known people on the second movie (the late donna summer) and then I think on the 3rd movie on, they started using inhouse songs for the dub.
By googling M2M, they were basically one of those splash in the pan girl groups that were common back in the late 90s early 2000s. I had sorta forgot about those girls. ^^;
