Fifteen months and five Hot 100-topping singles after Katy Perry released her Teenage Dream, the album keeps yielding new music videos. This time it's for "The One That Got Away," which features Perry in some hardcore Benjamin Button makeup. The video is like the ultra-sad opening scene from Up combined with the ultra-confusing final scene from 2001: A Space Odyssey with a whole bunch of flashbacks tossed in.

The second-worst-kept secret reunion in music was confirmed at 11:11 a.m. PST today as Black Sabbath's original members — Ozzy Osbourne, Tony Iommi, Geezer Butler, and Bill Ward — finally confirmed that they are reuniting for a new Rick Rubin-produced album and a long tour in 2012. The band made the announcement at a special press conference at Hollywood's Whisky a Go Go, where Sabbath played their first Los Angeles gig on this date (11/11) in 1970. So far, the band has booked only one concert -- England's Download Festival on June 10, 2012 -- but they'll embark on a massive trek after that. "It's like putting on an old glove. It's fantastic," Iommi said of the reunion.

EMIAnd then there were three major labels: After nine months of Citigroup-owned limbo, the beleaguered EMI, which was the most successful of the Big 4 record labels not too long ago, has been split in half and sold off to two of its former competitors, Sony and Universal. According to Billboard.biz, Sony has purchased EMI Music Publishing, while the overgrowing Vivendi/Universal Music Group picked up the crown jewel, the EMI recorded music division, which includes the works of the Beatles, Pink Floyd, pre-2007 Radiohead, and a roster that currently includes Coldplay, Gorillaz, and Katy Perry.

Rocawear.comThanks to Jay-Z, you can now purchase solidarity and wear a mass-distributed symbol of grassroots anger. Always looking for ways to satiate the wealthiest segment of the population, proud 1% member Shawn Carter has created a t-shirt line to capitalize on the headline-grabbing Occupy Wall Street movement. The new Rocawear tee—which comes out today—reads "Occupy Wall Street" in stark white letters but scribbles out the 'W' and throws in a red graffiti-style 'S,' making the message "Occupy All Streets" instead.

Business Insider was kind enough to contact Rocawear and determine that the corporation is not familiar with the concept of irony. "At this time we have not made an official commitment to monetarily support the movement," a spokesperson for the $700 million-earning corporation said, although they acknowledged the $22 shirts are "created in support of the 'Occupy Wall Street' movement."

To celebrate this momentous, once-in-a-lifetime occasion, The Amp has plunged deep into our iTunes to create this playlist, featuring our favorite Track 11s. By no means is this a "best of" list; it's just our personal picks of those pivotal songs that show up toward the end of albums.

Enjoy the "Six Ones Day" party with these cuts:

You Da OneOutside of first single "We Found Love," Rihanna has kept a tight lid on her upcoming album Talk That Talk. But with the disc due out November 18th, the singer decided to whet the fans' appetite by premiering a new track called "You Da One," one of the few radio-friendly songs on the very dirty TTT. The single is textbook Rihanna with its trademark stuttered hooks, islands-tinged sound, and lyrics about obsessive love. "You the one that I dream about all day, you the one that I think about always," Rihanna sings on the chorus. And like all singles these days, there's the prerequisite dubstep breakdown in the final third of the song. Compared to the universally praised smash "We Found Love," "You Da One" definitely falls into the category of lesser RiRi singles like "Man Down" and "Russian Roulette," but there's no way a song this catchy won't result in yet another Top 10 hit for Rihanna:

When it was announced that producer extraordinaire Brian Eno would be the guest on last night's The Colbert Report, no one could have anticipated this would happen: Michael Stipe, Colbert, and Eno singing a rendition of Bill Withers' "Lean On Me" together. With R.E.M. calling it quits, we figured it'd be a while before anyone heard Stipe sing again, but there he was, enshrined on Colbert's Rock & Roll Shelf of Fame, since R.E.M. was the first band to ever perform on Colbert's show. The host does a great job harmonizing with the two vets, but just the image of Eno and Stipe singing together makes this one of the late-night music highlights of 2011. It's just a shame R.E.M. never linked up with the producer during their run.

Did you purchase tickets for an Adele concert that ended up being canceled? Here's a new DVD to rub that disappointing feeling back in your face: On November 29th, the British songstress will release her CD/DVD Live at the Royal Albert Hall, which features her entire September 22, 2011 performance from London's most famous venue. The gig was filmed after Adele canceled her first U.S. tour but before she nixed her second U.S. trek, so it was that brief moment in 2011 when the singer wasn't overly affected by "recurrent vocal cord bleeding from a benign polyp." Lasers have since saved her voice.

Over four million Americans have already purchased Adele's 21 this year, but with Black Friday just weeks away, the singer needed to release something new to capitalize on the sales surge. Unfortunately, because Adele is still recuperating, she won't be able to promote the DVD herself, but her team has figured out a solution: Live at the Royal Albert Hall will premiere at movie theaters in New
