i disagree, i think it depends on the person, but singing properly can be a lot harder then screaming. the thing with singing is findin your own voice and not trying to replicate any other artists voice - thats the difficult part (singing lessons will take care of the technical part of it all, but not the finding your own voice part), i can scream pretty well nowadays but i'm still mastering the whole singing part. but then again some ppl might have a natural nack for singing and find it harder to scream. its very subjective.
