Robert Plant no longer wants to front Led Zeppelin but we can't allow Pussycat Doll (and new X Factor judge) Nicole Scherzinger to take his job because that is all kinds of wrong. However, in case of Led Zep emergency, please call Karen O. Thanks to a videographer who captured the new "red band" trailer for David Fincher's adaptation of the Swedish bestseller The Girl With the Dragon Tattoo, the Yeah Yeah Yeahs frontwoman's collaboration with Trent Reznor on 1970's "Immigrant Song" is all over the web. Reznor (who is scoring Dragon Tattoo) has replaced the song's octave-jumping, see-saw guitar riff with murky, moody synths and emphasized ominously pounding percussion while Karen O brings the hammer of the gods, shrieking and snarling her way through the greatest song about a Viking invasion ever recorded. Valhalla, I am coming!

(Also: The movie looks pretty cool!)

(Also also: Wikipedia informs us "The song was placed over an animation of kittens in Viking costumes on rathergood.com"

On June 28th, the Wu-Tang Clan will release what's being advertised as their new album, Legendary Weapons. But is this really a new Wu album? We have some concerns that something fishy is going on in the 36 Chambers.

First clue: Debut single "Only the Rugged Survive" features the RZA rapping, and only the RZA rapping. That's strange, since the single artwork announces the track "features RZA," instead of it being a foregone conclusion that the mastermind is involved. Check out "Only the Rugged Survive" at Nah Right.

Second hint: The album is coming out on E1 Music, the label that's released not-quite-real Wu albums like 2009's Chamber Music. On these discs, leftover verses are strewn together under one beat and packaged as real deal Wu recordings, even though the last official Wu-Tang album was 2007's 8 Diagrams.

What's promising about Legendary Weapons is all of the core members are on it (according to a press release). Ghostface Killah, who was reduced to almost a spectator on 8

Who isn't delighted by Suck It and See, the name of the Arctic Monkeys' awesome (trust us, we've heard it) fifth album? The Amp enjoyed it so much, we made up our own album cover. And last night, David Letterman rewarded himself after a hard week haggling with Lady Gaga by pronouncing the title, pausing dramatically, and adding, "I'm being told it's their Christmas album."

Letterman likes his hard rock -- he's a famously huge Foo Fighters fan -- and "Don't Sit Down Cause I've Moved Your Chair" explodes into a hefty riff that shows the Sheffield quartet haven't shook off the influence of Josh Homme, who coproduced 2009's Humbug. Alex Turner and Co. kicked it out perfectly. Watch it and see:

While news that the Grammys are cutting 31 categories from its bloated award show sat well with viewers (us included), some folks are less than pleased with the decision to dump what they see as opportunities to honor ethic music. At a press conference in Beverly Hills yesterday, a coalition of performers protested the restructuring of the Latin field (downsized from seven Grammys to four) and the removal of the Latin Jazz Album Grammy from the Jazz field. "We will not be disenfranchised," the group wrote in a letter to the Grammys.

Paul Simon and Herbie Hancock both support the coalition, and Carlos Santana, who just last week accosted Atlanta-area baseball fans over anti-immigration laws, also protested the slimming of the Grammy field. "To remove Latin Jazz and many other ethnic categories is doing a huge disservice to the brilliant musicians who keep the music vibrant for their fans -- new and old," Santana wrote.

Musician Bobby Sanabria, the leader of the coalition and a
