Lady Gaga in the "Cake" preview

Lady Gaga appears to be rapping on what's shaping up to be a new album cut "Cake." Mother Monster released a luscious little clip of her speak-singing along, with images of wagging butts, dancing in her underwear and otherwise suggesting that a lucky piece of cake is going to get some action from a very famous pop star.

"You chew beef, I wear meat / And stay on top of the I'm I'm I'm I'm / Getting fat and so is my bank /With a sold out world tour b*tch," are among the lyrical sage-wisdom, as the song was also previewed during a Mugler fashion show in September.

As for the 15-second clip, maker-of-sexy-photos Terry Richardson helmed it, which should surprise no one. Gaga and Richardson released a photo book together just last year. And Richardson likes things to look like an American Apparel ad.

Chris Brown and Rihanna's new duet "Ain't Nobody's Business" is, indeed, "Unapologetic." The song has arrived in full a few days out from Rihanna's new album release, and the pair would like for detractors of their rebudding relationship to butt out.

Using a famed line from Michael Jackson's "The Way You Make Me Feel," they both sing on the refrain: "It ain’t nobody’s business / Just mine and my baby." The sound, overall, is reminiscent of MJ, which must've thrilled the pants of Chris Brown, a longtime disciple who has never shied away from the comparison. It's helmed by The-Dream.

With lines about making out in a Lexus and the continued use of "baby," one would assume that Rihanna and her baby are back together, which they've both denied in the past week. The question of their relationship status, however, will never cease to pique others' curiosity so long as Rihanna and Chris Brown make songs like "Nobody's Business." Making their business model dependent on "Nobody's Business." Business because of "Business." The snake eats it tail.

"Nobody's Business" is a decent song, if you're in a place to hear it. I think it's lame to drum up publicity based on the reformation of what I think is a screwed up relationship that should truly be addressed quietly, but if Brown-Rihanna duets are the MO in the future, so be it. This is one of the cases where the public persona plays deeply into how songs are written and performed, making their personal business of "Business" fair game in criticizing it. So it's a draw, in consideration of her deeply affected delivery of the words "hain nobah'ees bi(d)neh," Brown's bad edits on the pre-chorus, the "infectious" post-disco dance brew and wrinkle-nosed funk at the end.

Yo La Tengo's "Fade"

After an intense election season, a week of scandal, a big "Bond" premiere and that disappointing new Why? album, it's about time for something uplifting and easy to listen to. Yo La Tengo may fill that gap, with the promise of a new album "Fade," due on January 15.

The band released an EP, "Stupid Things," earlier this year, and have included the title track in the 10-song list for this fresh effort. You can hear it below. You may find your ballot-casting hand a little less shaky, or your headphones finally relieved.

Pre-orders are up now and a deluxe version gets you a 7″ with covers of Todd Rundgren’s “I Saw The Light” and Times New Viking’s “Move To California.”

Yo La Tengo is touring in support, starting with their Hanukkah concerts at Maxwell's in New Jersey, and continuing with some shared dates with Calexico. Check those below.

From "Wild"

Did I say the "Twilight: Breaking Dawn - Part 2" soundtrack would bum you out? I take it back. The video to Beach House's excellent dream-world "Wild" will bum you out.

And you thought your life was a wreck.

Johan Renck helmed this little spot of violent sexual sunshine, and it may not surprise the viewer that he directed episodes of "Walking Dead" and "Breaking Bad," too. (It may furthermore surprise that he's directed clips for Kylie Minogue and Madonna.)

"Wild" is off of "Bloom," released earlier this year.

Before I start in on Christina Aguilera and CeeLo Green's live debut of her "Make the World Move" duet, a couple things:

1) People are doggin' on Xtina for the weight gain, and have for a while. I've always thought she looks mega-fine, the added pounds or not. Criticisms of her appearance have frequently preceded any salient thoughts on her talent, which is ever-impressive.

2) CeeLo Green operates best with specific confines. Give him a retro sound, and he's brilliant. Give him a costume concept and he's all in. Give him 10 minutes aggregate of a TV talent show and he's unstoppable. CeeLo doesn't dance. He grooves and gets out of the way.

3) "Make the World Move" is a generally likeable song off of "Lotus."

Now. The television performance of "Make the World Move" on last night's "Voice" (Nov. 13) was positively batty.

Madonna and Psy

Psy's "Gangnam Style," with all its idiosyncrasies, will go down in the annals as epically robbed at No. 2 on the Hot 100, never to see No. 1, occupying the eternal runners-up prison where Boyz II Men's "Water Runs Dry" and Gnarls Barkley's "Crazy" sit, shivering.

That is, unless Madonna's endorsement helps that last strong push. (Or not.)

Culling what one can from the music video for "Breathing Underwater," Canada's Metric is a popular band and performs and popular events, and deserve to anyhow. It would also be exhausting to be them.

That seems to be it.

"Breathing Underwater" is from Metric's "Synthetica," released in June; the album is getting a deluxe re-release this month, with five acoustic tracks tacked on. The shiny new version will be out Nov. 20 via digital retail and Dec. 4 at brick and mortar.

Ludacris in "Rest of My Life"

The video for Ludacris' "Rest of My Life" featuring David Guetta and Usher is like one of those inspirational posters: it's a lot of monumental "moments" framed in motivational speech, but not without commerce. That is, look for the product placements inside this general message of carpe diem.

Sigur Ros have spent the better part of the last year revealing short films corresponding to each of the track off of their latest album "Valtari." As if something so ambitious cannot stand on its own, the Icelandic band is screening the 17 films on all seven continents -- including Antarctica -- and going on tour in North America and releasing an additional new EP of three songs.

They put their own ambition to ambitious shame.

The latest short film to be released from the album-film experiment is a movement-centered piece set to "Ekki Múkk”, “Valtari,” “Rembihnútur,” and “Varúð," featuring only a pair of dancers conversant in contortion, calling and responding through motion like a very intense mating call. Visually stunning, director Christian Larson's piece a great release after the pure tension of the tracks.

The screenings of it and other officially commissioned and fan-made videos for the "Valtari Mystery Film Experiment" will occur during the second week of December in some unorthodox venues like “hardware stores, hairdresser salons, and beyond," in dozens of cities worldwide based in Portugal to South Africa to Oklahoma to Japan.
