I'm happy for all the success that Beyonce has been having recently. The album is surprisingly consistent in a good way. I don't think there's much difference in quality between the singles and the album tracks. Also, I think the choreography from the Single Ladies video is slowly becoming iconic, which is something that hasn't been seen since Thriller in my opinion. Not to say that Single Ladies is as well-known as Thriller, but both have choreography that people know goes specifically with the song.
