Power Rankings have been rating sports teams throughout their seasons for years based on statistical analysis, momentum and gut feelings. Those folks shouldn't have all the fun.

Using our, er, proprietary technology -- based on sales and airplay charts, magazine covers, twitter trends, and, of course, gut feelings -- we bring you HuffPost's Pop Power Rankings, our weekly roundup of who's on top (and who has fallen off) in the pop game.

Previous Pop Power Ranking

  • 1. Rihanna (Last Rank: 3)

    With an album about to come out, you might expect Rihanna to, you know, cover the usual bases -- cool tour, awards show performance, a magazine cover. This is all true, but Ri Ri is taking this album SERIOUS. A$AP Rocky, the hippest thing in rap, will open for her on the tour, the award show performance will be with the man who's on probation for beating her (i.e. Chris Brown at this Sunday's American Music Awards), and she's basically <a href="http://www.huffingtonpost.com/2012/11/12/rihanna-nude-for-gq-singer-nearly-naked-men-of-year-cover_n_2119286.html?utm_hp_ref=canada-music&ir=Canada%20Music">naked on this month's GQ</a> cover. AND, in the GQ article she talks about wanting to get a face tattoo. Oh, and Daniel Craig said she would make a <a href="http://www.huffingtonpost.com/2012/11/12/daniel-craig-rihanna-beyonce-obama-bond_n_2117851.html">good Bond girl</a>. Clearly, Rihanna can do whatever she wants.

  • 2. Justin Bieber ( Last Rank: - )

    Ah, there's nothing like a break-up to separate the pop men from the pop boys. Bieber is taking a short break from his world tour, but he's still finding his way to the top of the PPRs. In the face of a <a href="http://www.huffingtonpost.com/2012/11/13/justin-bieber-selena-gomez-break-up-rumors-ridiculous-headlines-jelena-edition_n_2121543.html">public break-up with Selena Gomez</a>, Justin has managed this week to <a href="http://www.huffingtonpost.co.uk/2012/11/11/mtv-ema-awards-taylor-swift-justin-bieber-one-directio_n_2115091.html">tie Taylor Swift</a> winning the most MTV EMAs (3), allegedly hook up with <a href="http://www.vh1.com/celebrity/2012-11-13/15-photos-of-victorias-secret-angel-barbara-palvin-justin-biebers-alleged-other-woman/">Victoria's Secret model</a> Barbara Palvin, and sing a winking live cover of Justin Timberlake's fame-break-up kiss-off <a href="http://www.huffingtonpost.com/2012/11/12/justin-bieber-cry-me-a-river-selena-gomez_n_2116623.html?ir=Entertainment">"Cry Me a River." </a>Sorry, Selena, but point to JB.

  • 3. Taylor Swift (Last Rank: 1)

    Europe loves Taylor too, as she just took home three awards -- Best Female, Best Live, and new award Best Look at the <a href="http://www.huffingtonpost.co.uk/2012/11/11/mtv-ema-awards-taylor-swift-justin-bieber-one-directio_n_2115091.html">MTV EMAs</a>. And look-wise, she looked stunning in her most glamorous <a href="http://www.huffingtonpost.com/2012/11/12/emas-2012-photos-red-carpet-mtv-european-music-awards_n_2116112.html?utm_hp_ref=canada-music&ir=Canada+Music">red carpet outfit yet</a>. But that's not what brings the power. We're still under the influence of her album <em>Red</em> making the best sales debut in 10 years, readying ourselves for this Thursday's <em>X Factor</em> performance, and reading think-pieces trying to explain (or dimiss) her success.

  • 4. Adele (Last Rank: -)

    It's no surprise her <a href="http://www.huffingtonpost.com/2012/10/04/adele-skyfall-james-bond-theme_n_1940645.html">James Bond anthem "Skyfall"</a> is number one at iTunes. James Bond and Adele both sell. What's refreshing is that she's still endearingly "normal." After having a baby boy she's refusing to reveal his name to the press, and refusing to get a nanny despite being reportedly one of the highest earning musicians of recent years. If that doesn't make you love her even more, this week <em>Adele: The Biography </em>hits bookstore shelves, and includes quotes like this one on her body image: "I read a comment on YouTube that I thought would upset me 'Test pilot for pies' -- but I've always been a size 14-16 and been fine with it. I would only lose weight if it affected my health or sex life, which it doesn't." A pop star with the power to be herself? That ranks.

  • 5. Trent Reznor ( Last Rank: -)

    The Oscar-winning composer, goth king and Nine Inch Nails mastermind recently released a very indie EP from How to Destroy Angels, his band with his wife Mariqueen Maandig. I know, that's not very "Pop." But, this week he also released the theme song to <em>Call of Duty: Black Ops 2</em>, the most anticipated video game release of the year. And while doing press for the theme song, Trent revealed that, indeed, Nine Inch Nails are getting back together. Sorry Trent, you're just too big to stay underground.

  • Pop Power Fail - Lil Wayne

    For years now, Lil' Wayne has transcended hip-hop into the pop world, but lately his health and legal troubles have been stifling his ranking. This week, Wayne lost a lawsuit against producers of the 2009 documentary <em>The Carter</em> over his "scandalous portrayal" (his lawyer's words) in this "awesome and fascinating film" (my words). But when Wayne was scheduled to appear in court for the suit, a <a href="http://www.huffingtonpost.com/2012/10/27/lil-wayne-released-from-the-hospital-migraine-deydration_n_2029716.html">medical emergency</a> kept him away. The result was a countersuit from the producers that awarded them over $2 million of Wayne's dollars. And if his plummeting musical stock still matters to you, Wayne reacted by pushing back the release date of his next album <em>I Am Not a Human Being 2</em> into 2013.
