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 RANKINGS

Loading Slideshow...
  • 1. One Direction (Last Rank: -)

    Pop power may not be measured in Mick Jagger mentions, but it doesn't hurt. Jagger recently said 1D remind him of the early Rolling Stones with their awkward stage presence. After watching them on the telly he remarked that they looked "really distinctively uncomfortable." That may not sound like raw pop power, but their second album made history on the Billboard charts this week, debuting at number one -- the first time in history that a British artist's first two albums topped the chart -- with 540,000 in sales, the second highest of the year and, more importantly, besting Bieber. Oh, and One Direction are the ONLY musical act that will appear in Barbara Walters' Most Fascinating People of 2012 special on Dec 12. Which one's on cry duty? We're betting Harry "maybe-possibly-dating-Taylor-Swift" Styles.

  • 2. Justin Bieber (Last Rank: 2)

    Justin was Artist of the Year at the American Music Awards this week, where he made sure to thank the haters (and where he was mauled by aged Playmate Jenny McCarthy). The recent photos of him in drop-crotch pants begging Selena to let him into her house? Not helping. But, he took on his hit single "As Long As You Love Me" at the AMAs in acoustic form with much success, including rap-singing (and kinda outdoing) Big Sean's verse and. Artist of the year proves his musical talents yet again, then he goes through a humbling experience with an ex and appears human (despite the pants). This is the Justin Timberlake blueprint, people! Oh, and remember when he fought that paparazzi photographer? He gets to keep the street-cred but the assault charges were dropped.

  • 3. Rihanna (Last Rank: 1)

    How's Rihanna's week for power plays -- RiRi trapped reporters and fans on a <a href="http://www.huffingtonpost.com/2012/11/19/rihanna-777-tour-unapologetic-star_n_2148554.html?utm_hp_ref=canada-music&ir=Canada%20Music">week-long plane tour</a> "with" her (RiRi's most noteworthy appearance was at the end to apologize for not being around). This created a week of blog updates from major news outlets... complaining about never seeing Rihanna. Dick move? Maybe. Incredible amount of publicity without putting Rihanna in front of reporters where she might act out? Genius.

  • 4. Psy (Last Rank: -)

    Psy closed out the AMAs by bringing out MC Hammer, and they traded off their signature dances. Bravo, Psy, for pre-emptively turning potential one-hit-wonder criticism into more campy entertainment. Meanwhile, "Gangnam Style" is somehow still on its way UP the charts, and there are rumours of an MC Hammer duet to go with earlier reports of a Bieber duet. Ladies and gentlemen, Psy is not horsey-riding away anytime soon.

  • 5. Ke$ha (Last Rank: -)

    Ke$ha's new single "Die Young" has been working for her at radio for a while now, but this week her tribal-drumming, confetti-cannon of a live show hit television in a big way with the AMAs, Aussie <em>X-Factor</em> and the Today Show. This is proof that Kay-Ee-Dollar-Sign-Ay can throw her weight around in the pop world. And as for being an original, she also revealed this week that she<a href="http://www.huffingtonpost.com/2012/09/29/keshas-ghost-sex-claim-_n_1924336.html"> slept with a ghost</a>, did not <a href="http://www.huffingtonpost.com/2012/11/05/kesha-justin-bieber-singer-not-have-sex-justin-bieber_n_2078570.html">sleep with Justin Bieber</a> and made a <a href="http://www.huffingtonpost.com/2012/11/21/kesha-bra-from-fans-teeth_n_2170202.html">bra from her fans' teeth</a>. Something tells me her label's "fan engagement specialist" didn't come up with that.

  • Pop Power Fail - Aerosmith

    Sources close to Aerosmith's chillingly received Global Warming comeback tour have leaked that band members are barely speaking to each other. The band has denied the rumours, but they can't dispute that none of the shows are sold-out, and their first album in a decade debuted at number five behind <em>Now That's What I Call Music 44</em> and Rod Stewart's Christmas album. Not-so-sweet emotion, guys.
