Although he has had his rough moments, Scott has been my favorite rock singer for years and that will probably never change. When it comes to actual albums, I think Scott's vocals are at their most powerful on Core but would give the "best all-around" award for his performance on Purple. And I see some comments bashing Libertad and once again, I'll stick up for it by saying I think his vocals on that album are amazing, and I guess very underrated. His vocals on Contraband can be pretty "eh" at times to me
