Dance hits are starting to get a little better in terms of quality. I'd say that Swedish House Mafia's gotten the best electronica/dance top ten hit in the past decade or so. And personally, I find that Scream & Shout is a step up from some of what we've previously had.
"I Cry" does not belong in the top ten, but radio will be radio.
And "Beauty And A Beat" has done all that it can do. Justin's next single will probably be from the acoustic album that he''s releasing in two weeks.
