NEW YORK (AP) - His new hit "Blurred Lines" is being heard everywhere - and the video is getting lots of peeks, too. But Robin Thicke says he wonders if all that would have happened if he hadn't already established credibility as an Urban artist. The singer notes it's rare these days to have a song playing on both pop and urban stations. Thicke says he doubts the song would have gotten more play if he were a new artist. Speaking of doubts, Thicke says he wondered if his career was about to hit the skids as he approached his newest album. He says he decided to "push the boundaries" and work with some proven hit-making producers. He's happy with the results, especially because he says he "didn't have to change" the type of artist he is and the type of music he likes making.
