At long last, the collaboration the world has waited for with baited breath. Slipknot and Justin Bieber come together to form the ultimate mash-up of the ages, "Psychosocial Baby."

Button-enthusiast, Dalton Stevens, really loves buttons. How much does he love buttons? So much so that he wrote a song about them. "Buttons can be square or round, they keep my pants from falling down." He's certainly not wrong.

Nick Pitera, of the Youtube famous "A Whole New World" one-man duet is back with another impressive Disney performance - this time, showing off his incredible vocal range as he goes through a medley of all your Disney favorites.

Well done, everyone! Rebecca Black, the Ark Music Factory product whose teen dream song about days of the week "Friday" went crazy viral last week, has had her song downloaded over 2 million times on iTunes. Meaning, she's probably already a millionaire! From Forbes.com:

Music site Spinning Soul reports that R&B/disco legend Loleatta Holloway died "following a brief illness." Holloway, who started her career as a gospel and R&B singer, found success as a disco act in the late 1970s—but she might be most famous for providing the hook for Marky Mark and the Funky Bunch's "Good Vibrations" (a sample from her "Love Sensation.") Above, Holloway performing "Hit & Run."

On tonight's episode, Conan O'Brien announced that he was "pretty mad at this Rebecca Black person." Why? Because she ripped him off! According to O'Brien, Black's "Friday" is a total copy of his song, "Thursday." Here's the music video.

Did you know that Kirstie Alley is 60 years old? Did you know that she's a contestant on this season of Dancing with the Stars, which premiered tonight? Did you know that she actually danced a really good Cha-cha-cha?

Biran Haners parody of Rebecca Blacks Friday entitled Saturday is less bubble gum pop and more about hookers, cocaine, and murder. Saturday, Saturday another day to party.

Sometimes the best plan of action is to simply wander down Austin's main streets without a set schedule, ducking into parties at random as you find them. SXSW is filled with the chaos of too much happening at once and that's especially true on the final day when brands, bands and attendees try to cram in everything that didn't fit during the days prior.

YouTube user Fagottron has made some incredible songs by cutting together sounds from a movie, and he's done it again with this Lord of the Rings remix. So listen, and break it down like the dirty little orc that you are.

Watch FSU's co-ed a cappella group, All-Night Yahtzee, perform a Disney Villain Medley that brings down the house! From Ursula to Scar, it's the baddies' turn to shine.

Day three of the music portion of SXSW continued in sun-drenched fashion. While many of the fest's most hyped musicians meandered about the streets, much of the action and popular day parties centered around Red River street, from Spin's event at Stubb's to Club De Ville, Beerland and more.

Legions of green decorated the streets of Austin yesterday as day two of the music portion of SXSW coincided with St. Patrick's Day. After various parties, loft retreats and even a vegan BBQ hosted by Moby during the day, Thursday night's big draw was a free outdoor concert by the Strokes. And in keeping in Texan fashion, the event was large in size, taking over an entire field and culminating in a fireworks display during the group's last song. Here are some photos of yesterday's action.

Check out to this almost listenable cover of the now infamous Rebecca Black song done at an event raising money for The Red Cross to aid Japan. He so committed to performing the song he even does the rap.

Teen meme Rebecca Black was on Good Morning America today talking about the ridicule and fame brought by her "Friday" music video. She seems to be handling it pretty well, even if some of the mean YouTube comments made her cry.

On tonight's American Idol, we were again subjected to a cheesy group number. And while not nearly as intolerable as last week's Michael Jackson medley, this "Born to Be Wild"/"Born This Way" mashup left much to be desired.

First, there was the unforgettable original version. Then, there was the cool, laid back, arguably better-than-the-original cover. Now, Rebecca Black's "Friday"—the song that captivated the country for all the wrong reasons—has its ominously emotional cover. It's pretty good!

Here's video straight out of SXSW of Jack White playing in front of his "Third Man Records Rolling Record Store." The vehicle serves as a store, recording studio, and also the backdrop for this very-cool set.

What better way to honor St. Patrick than to shake your rump to a song about backsides? Allow Blarney and his clown sidekick to serenade you to Savage's "Hips Swing" on this fine holiday.

Under overcast skies, the music portion of Austin's annual SXSW festival kicked off yesterday. While Wednesday is seen as more of a precursor to the higher profile headliners and bigger parties that the weekend brings, throngs of people turned up at the various venues and tents for the fest's launch. With free booze flowing thanks to all the sponsors who have descended on the event in recent years, we ducked into a handful of shows including an especially energetic set from Alabama rapper Yelawolf before capping off the evening with the live taping of MTVu's Woodie Awards.
