Back in 2007, Beyoncé did something very interesting.  She released a video anthology for her album 'B'Day' which included a music video for every song on the album.  I think it's a great thing to do because then you get to see the artist's interpretation of each and every song.  Beyoncé's at it again with '4', so '1+1' is the first offering off of the anthology.  The video is very dark and sensual with Beyoncé sweating and singing into the camera for most of the video.  She's always at her best when she does this kind of thing because she is showing the true emotion and vulnerability that she harbors deep down inside.  The video is entrancing and made me love the song even more.  Walking around the NYU campus today I have been singing this song in my head.  Can't wait to see which video will be coming next!
