"Our first guest is a good friend of the show. He... oh, screw it." If there's a silver lining in Justin Timberlake ditching his music career to become an actor, it's that the (former) singer's many movie roles allow him to visit Late Night With Jimmy Fallon every few months. The In Time star and Fallon wasted no time launching into the third volume of their beloved "A History of Rap," featuring hip-hop favorites by Young MC, Jay-Z, Kanye, and Naughty By Nature. It wasn't their sharpest lesson -- their brief rendition of J.J. Fad's "Supersonic" could have used more rehearsal time -- but it was worth it just to hear Fallon rap Ice Cube's benevolent rhyme, "I didn't even need to use my AK."

Here's the setlist, and click here to relive A History of Rap, Part One and Part Two:

Earlier this week, an old hair band called Kid Rocker accused Poison, and especially guitarist C.C. Deville, for stealing the riffs that eventually became the hits "Talk Dirty to Me" and "I Won't Forget You." It took over 25 years for the copyright infringement lawsuit to finally materialize, and less than a week for Bret Michaels and company to comment on the accusations. According to the Hollywood Reporter's Hollywood Esq. blog, Poison says Kid Rocker's claims have no merit, and that they'll seek to dismiss the lawsuit.

"Poison will vigorously defend against the baseless accusations alleged in the complaint," Poison's attorney Mark D. Passin said. "Obviously, if the Poison songs that are the subject of the complaint infringed any songs written by Plaintiffs [Kid Rocker's Billy McCarthy and James Stonich], they would have filed their lawsuit over 20 years ago when Poison released the albums on which the songs are embodied. It is unfortunate that success in the entertainment business

Need a terrifying way to spend Halloween? Instead of going to a corn maze or trick-or-treating while dressed as Nicki Minaj, sit down in front of the computer and listen to a new Flaming Lips song called "7 Skies H3." Not exactly Stephen King stuff, but there's a catch: The track is 24 hours long. Starting at midnight on October 31st, Oklahoma City time, Wayne Coyne will stream the band's newest aural Frankenstein. The song was originally packaged in one of those gummy skulls that the Lips have used to distribute tunes lately, but listen to "7 Skies H3"on the new website FlamingLips24HourSong.com. The site's Bookmarks icon is also a marijuana leaf, so that's a little clue on how this frightening track should be experienced.

The Amp fearlessly live-blogged the Lips' six-hour song "I Found a Star on the Ground," and that assignment was like mountain climbing while someone jackhammered our skull. It almost permanently ruined The Soft Bulletin for us. To take that long, long experience

From this point on, anytime you ever think about Reckoning or Automatic for the People, images of Bring It On and Crazy/Beautiful will pop into your head. R.E.M. called it quits last month, but not before filming a pair of videos for "We All Go Back To Where We Belong," a new track off the band's upcoming greatest hits comp Part Lies, Part Heart, Part Truth, Part Garbage: 1982 - 2011. And what better way to call it a career than with actress Kirsten Dunst.

The video is, no joke, the actress doing nothing for 3 minutes and 39 seconds. We shouldn't say "nothing," since at the 2:27 mark, Dunst takes her loose hair and assembles it into a ponytail. That's literally the Act II climax of the "Kirsten Version" of "We All Go Back To Where We Belong." It's like one of those experimental Warhol films they forced us to watch in film school. (On the bright side, the song's pretty excellent, and a nice way for R.E.M. to cease making music together.)

In the battle of bare bones, one-shot music
