If Rihanna's "Pon de Replay" left you wanting more from her in "Dance Central," this is your lucky day because she's also made "Disturbia" available for the Kinect title this week, along with tracks from Blur and Janet Jackson. She joins previous DLC contributors Ne-Yo and Lady Gaga in the "DC" marketplace, where Sean Paul and The Black Eyed Peas have also put themselves up for sale.

Their tunes run 240 MS points apiece there, and the library is still young, but it's growing. This week's batch of tracks marks Blur's debut with their track "Girls and Boys," and the same goes for Janet Jackson, who's entered the "Dance Central" DLC ring with her 1986 single "Control."

So whether you're hanging around inside wearing your sweats, torn between the urge to get outside to be active and your fierce aversion to the cold of winter, or just want to test out your GWAR costume with "Dance Central" and have been hesitant because you needed a Blur track to materialize, your time is now.

"Blur" excites me the most off of this list, and if the "DC" folks wanted to just start making deals to build all-"Blur"-and-"Prodigy" sub-stores for their game, I would love to hang out there for a significant amount of time every week. They are off to a fine start with "Girls and Boys," though.

Ke$ha 'totally fine' with Rihanna

Pop star Ke$ha has brushed off reports of a feud with Rihanna after the Umbrella hitmaker appeared to make disparaging comments about her pop peers.

The Bajan beauty stirred controversy in October when she revealed all of the songs on her new album Loud would be written especially for her, unlike some other tracks in the pop charts.

She was quoted as saying, "I didn't want the generic pop record that Ke$ha or Lady Gaga or Katy Perry would do. Every song is tailored to me."

Rihanna's comments were alleged to have sparked a pop rivalry among the stars - but Ke$ha has paid little attention to the rumours and she's confident the media is responsible for turning it into a big deal.

She tells Complex magazine, "I haven't even read that. I'm so used to the media flipping my words around that I'm sure she meant absolutely no offence to me or Katy or Gaga - Rihanna and me are totally cool, we were just on tour together, and I know that she and Katy are good friends."

Ofcom confirm Rihanna and Christina Aguilera 'X Factor' probe

Eight days, a handful of lurid, full-colour tabloid photo spreads and 2,750 complaints later: Ofcom have finally been cajoled into investigating Christina Aguilera and Rihanna's allegedly "raunchy" 'X Factor' performances, the NME reports.

Nearly 20 million people watched the 'X Factor' finale -- in which Matt Cardle took home the seventh series crown -- on 12 December 12. Along with those who contacted Ofcom, 1,000 viewers reportedly complained to ITV about the two guest performers' underwear-clad dance moves on the Sunday evening special.

The Daily Mail has been drumming up outrage over the Aguilera's rendition of her hit 'Burlesque' and Rihanna's version of 'What's My Name?', calling them "lewd" and quoting "horrified" parents -- while helpfully publishing large format photos of the offending routines "to show the fury they've caused".

Mail columnist Jan Moir -- herself no stranger to complaints, after prompting record numbers with a 2009 piece that argued late Boyzone singer Stephen Gately's "sleazy" lifestyle was to blame for his death -- wrote that "crotch flashing and pseudo sexual grinding" were "out of place before the watershed".

Ofcom will now attempt to figure out whether the X Factor finale broke section 1.3 of the broadcasting code, which insists that "children must be protected by appropriate scheduling from material that is unsuitable for them".
