Thanks for these additions, guys. I am always happy to expand the list.

I should probably clarify, however - my list was primarily meant to be MHR-type acts. Granted, there are some acts on it that walk the line between pop and MHR (Bryan Adams, Platinum Blonde, Red Rider, etc.). But I did leave acts like Avril Lavigne, Shania Twain, Celine Dion, etc. off for a reason. Same with acts from the post-grunge movement like Nickelback, Default, Theory of a Deadman, Finger Eleven, Three Days Grace, Thousand Food Krutch, Faber Drive, etc.
