Antivalentine?

I heard this song months ago and have been OBSESSED with it ever since.  I mean, ridiculously obessesed.  Playing it over and over again in the car and singing as loudly as possible.  Much to the chagrin, I am sure, of other drivers.  In the past couple of weeks I have been hearing/seeing every where.  And I, of course, am feeling quite smug that I have been in love with it for months.  I saw it touted today as an "antivalentine" song.  I am not really sure about all of that, but what I do know is that her vocals on this are AMAZING.  Enjoy!
