I thought Natalia Kills 2011 debut album was a pretty rad slice of sytnthpop with just enough edge to it to make it cool. But while I liked Perfectionist, it never really found its way into my "heavy rotation." Well Problem, the first single off her upcoming album Trouble, won't suffer from such a fate. It's killer industrial rhythms and punchy vocals make it a can't miss summer smash. Oh, by the way, it's hot as hell and I thought that way well before I saw the video . . . be warned, it's a bit racy.
