Power Rankings have been rating sports teams mid-season for years, based on statistical analysis, momentum and gut feelings. But there's just as much strategy and move-making involved in the big leagues of pop.
So, we bring you HuffPost's Pop Power Rankings, our roundup of who's on top (and who has fallen off) in the pop game.
1. Justin Timberlake (New Entry)
You'd hope for his sake that the man who bought Myspace has figured out the internet, and based on the past couple of weeks it looks like JT has. After surprising everyone with 1-minute video teaser, he released new single "Suit & Tie" along with an open letter to his fans. The new song hit the charts this week with the highest sales week ever for a JT number. Good to have you back doing what you do, Justin. Which, for the record, only sort of includes movies.
2. Beyonce (Re-Entry)
Her HBO documentary (that she directed) just got a <a href="http://youtu.be/I1mkntvbS8w" target="_hplink">teaser,</a> she's next month's Superbowl half-time show, and her new album should be out this summer. But that's not enough for Beyonce. In the meantime, Destiny's Child have released a new song, have agreed to reunite at the Superbowl show, are putting out a compilation of their best love songs, and the platinum-selling supergroup are still just a stepping stone in Beyonce's 2013.
3. Taylor Swift (Last Rank: #1)
Oh no, Harry from One Direction! One minute Taylor Swift is your girlfriend and you're going on sweet dates to shop for things in front of paparazzi, and the next thing you know, her bodyguard takes her number out of your phone and she's tweeting photos of her with her notepad and guitar writing songs about you. If only Harry Styles could have seen a Taylor boyfriend-pattern emerging.
4. Nicki Minaj (Re-Entry)
<em>American Idol</em> is back, and it's looking like Nicki's <em>American Idol</em>. Her hair's a colour you didn't even know your TV could achieve, and rival judge Mariah Carey can't compete because she looks like a normal person (she obviously didn't get the Gaga memo — weird wins). <em>American Idol</em> needed this concept of "rival judge," and Nicki is the one to bring it.
5. Rihanna (Re-Entry)
Fourteen weeks at #1 with her song "Diamonds" wasn't enough. Branching into the fashion world is up next for Rihanna. Not only is she signed on for her own fashion competition reality show, but RiRi has just been confirmed to show her first fashion collection (yes, as designer) next month at London Fashion Week. In a statement that she totally wrote herself she said appearing at Fashion Week was "a dream come true."
Power Pop Fail - Chief Keef
Chief Keef is barely on the edges of the pop world with his street-level hip-hop sound, but as a breakout star thanks to his hit "I Don't Like" it's fascinating to see him have such a bad week. First of all, Pitchfork interviewed him at a gun range, which violated his parole. He's serving 60 days in juvenile detention thanks to that web video (which has since been removed). Further, a show promoter in the U.K. just launched a lawsuit saying Keef didn't show up for his own show, and judging from his year of no-shows (including leaving 50 Cent hanging at his own video shoot), I think they may be onto something.
