its definitely B's worst single. i didnt like it, but then the video came out and made me like it. that was my favourite video of 2011. it had proper choreography and energy, not just gyrating. but its okay, not as good as beyonces other singles. terrible choice for lead single. 4 is either my 1st or 2nd fave beyonce album. it was such a strong body of work, not just a few hit singles, filler and a cringey ballad or two.
