According to Entertainment Weekly, "Hold It Against Me," the first single from Britney Spears' as-yet-untitled March album, will arrive January 7th. That's just eight days until fans get their first taste of the album Britney is in "L-O-V-E WITH"!

Sharon Dastur, the program director for New York's powerhouse pop station Z100 -- who has heard "Hold It Against Me" -- tells the magazine the song is produced by Dr. Luke and Max Martin, features an "infectious bass beat," and has a hook that is "just amazing."

Spears called the track "a monster" (how of the moment!) in a November tweet: "Just finished recording a monster with @TheDoctorLuke and #MaxMartin. Get ready.... -Britney."

Backing vocalist Myah Marie concurs that the song is fab. "The song is AMAZING, been stuck in my head on repeat," she tweeted, according to Britney fansite Breathe Heavy.

Dr. Luke tweeted, "Excited about this new music!!!!!" earlier this month, and then began a maddening game of revealing the tune's lyrics ("the

The petition to have the documentary "Michael Jackson's Autopsy: What Really Killed Michael Jackson" banished from European airwaves before its January 2011 debut might be a little light on signatures, but the fans' campaign did gain some pretty major support yesterday when both the Jackson estate and the Los Angeles Coroners' Office spoke out against the Discovery Channel special. As The Amp previously reported, "Michael Jackson's Autopsy" goes into grizzly detail to explain how the King of Pop died of cardiac arrest following an overdose on the powerful sedative Propofol. His death has been ruled a homicide.

Jackson estate co-executors John Branca and John McClain used a whole bunch of unflattering adjectives to describe "Autopsy" in a statement: "shockingly bad taste," "sickening," and "debased, sick and insensitive" -- and that was just to describe Discovery Channel's morbid advertising for the documentary, which depicts a covered corpse on a steel gurney wearing Jackson's

"Syllables," another song off Dr. Dre's near-mythical "Detox," crawled out of Dre's heavily guarded vault yesterday. While it's impossible that "Detox" will live up to its decade-in-the-making hype, "Syllables" at least proves that the album will feature some top-shelf tracks. Dre recruited Eminem, Jay-Z, 50 Cent, and Shady Aftermath signees Stat Quo and Ca$his to join him on a song that breathes fire on the music industry's reliance on younger MCs and hook-laden hip-hop rather than the smart fare Dre has served up for over two decades. Listen over at Nah Right.

"They said 30's the new 20, funny, must mean 40's the new 30, interesting, 'cause ever since there's been an extension for veteran rappers that are better than half the s--- that coming out right now, it's all trash, the torch is gonna burn out before it gets passed," Dre raps in a verse he probably didn't write about the dark future of hip-hop. Eminem then chimes in with one of those sing-along choruses that Em, Jigga, and Dre

San Francisco's DJ Earworm has dropped his United State of Pop 2010 -- a brilliantly woven mashup of the year's 25 most popular songs, as ranked by Billboard's metrics. His observation: 2010 music has been in full-on party mode. "Even the songs that aren't about parties have parties in their videos, like this year's entries from Mike Posner and Lady Antebellum," he writes.

Watch his also-awesome mashup video for more proof, and listen for how seamlessly all this year's songs blend into one another thanks to how much bloopy synth producers threw on everything made in the past 12 months. Don't look for too many guitars, though -- as The Amp already pointed out, you're not gonna find any. Full list of tracks in this mix is available on DJ Earworm's official site.
