Britney Spears Drops New Single "3"

Um...I really, really wanted to love this song but I'm just not sure about it. The beat is pretty fresh but the way it's sung reminds me of a hip Seasame Street song that's trying to teach me my 1-2-3's. I love Britney, but I'm just not sure about this song. What do you guys think? Is this track worth a second listen or are you as ambivalent as me?
