Kevin Rudolf's debut may have came across as some upcoming Lil Wayne's muse, but he is nothing like that. I feel like he went that route because his label made him, but inside he is bubble gum pop-rock.
He did produce and fully wrote Leona Lewis' "Love Letter" on her second album. He writes a lot for Jesse McCartney, Big Time Rush, Lifehouse... but I don't get why they try to make him look like this mini hip hop rock dude.
