"Radioactive," the gospel-tinged first single from Kings of Leon's forthcoming album, Come Around Sundown, might slow down the band's decent into Hell, says drummer Nathan Followill.

"I think after my grandma sees this video, she definitely doesn't think we're going to Hell as fast as she did think we were going," Nathan quips in a just-released teaser for the single, filmed on the set of their music video.

The "Radioactive" clip, which premieres Sept. 8, finds band hanging around a Southern barn, and backed vocally by a cute gospel choir of little kids in white shirts and black ties.

"Lyrically, the chorus started out being kind of spiritual, but the verses never matched up to it at all," bassist Jared Followill says of the song's roots. "We went into the studio, we tried it, and it wasn't really working, and we were going to scrap the whole song. Then Caleb went back to an old spiritual song that we all sang growing up, and it matched up with the chorus so nice."

"Gospel music was a big part of us growing up, so to be able to come back and revisit that part of our lives at this stage in our lives is a pretty special thing," Nathan adds.

The music of Las Vegas band Panic! at the Disco has always been heavily influenced by musical theater, so it makes complete sense that Panic bandmates Brendon Urie and Dallon Weekes have covered a song from the classic musical Little Shop of Horrors.

"Skid Row," posted for free on a new website, is mostly faithful to the original from the '80s off-Broadway sensation (and the 1986 feature film, which starred Rick Moranis and Steve Martin), and jazzed up with some Cars-y synth hooks and bursts of electric power chords.

Urie handles the vocals of Audrey, the musical's man-eating plant, while Weekes?who's been playing bass in Panic since the departure of Jon Walker and Ryan Ross last year?sings the parts of dimwitted Seymour Krelborn.

It's not known whether this is part of some larger project, but core Panic members Urie and drummer Spencer Smith have spent the bulk of 2010 working on the third Panic! at the Disco full length.

A full Radiohead concert video, shot and edited by fans at a 2009 gig in Prague, is now available for free download -- with the blessing of Thom Yorke and his bandmates. Find out how to get it below.

At the British rockers' August 2009 show at the Czech capital's V�stavi?t? Hole?ovice concert hall, about 50 fans with Flip video cameras positioned themselves throughout the crowd, filming the entire gig. Four different editors collected the footage and produced a finished concert film, which they posted on a website and on YouTube.

While Radiohead haven't publicly discussed the project, other than linking to the project's homepage from radiohead.com, they did provide the filmmakers with mastered soundboard audio from the show -- a de facto/pretty damn cool endorsement.

Rihanna
@rihanna

Why You Should Follow: Perhaps inspired by her friend and collaborator Kanye West?who jumped on the Twitter bandwagon at the end of July and instantly had more than 300,000 followers?Rihanna has finally joined the Twitterverse! Of course, she's had a verified account for quite some time now, but it was full of generic news updates from her publicists?nothing personal or interesting. That's about to change. Last Friday, she announced, "So now that i finally took over my Twitter page no more corny label tweets......lol! whaaasssuupppp ppl!!!!!" Since then, she's shared Twitpics of her brand-new, fire engine-red hair and the view from her hotel room in Hawaii. She also gave a shout-out to R&B singer and producer Ne-Yo, said to be a collaborator on her upcoming album, and teased radio host Ryan Seacrest about the release date for her first single "Only Girl In the World." Expect lots more from Rihanna as she gets ready to release the album, tours the world, hangs out with some of hip-hop's biggest names, changes her hair color every few weeks, and gets a new tattoo almost as often.

Best Tweet of the Week: "@RyanSeacrest Soon! In less than 10 dayz ima send u sumn special, and ur gonna play it OVER and OVER, like I?m the only girl in the world!"

Cee-Lo

@theladykilla

Why You Should Follow: Cee-Lo just released "Fuck You," an insanely catchy number that threatens to overtake Katy Perry's "California Gurls" as the unofficial Song of the Summer. The fun, colorful lyric video instantly went viral, and now that the official video has been released (on Twitvid, no less), the song is bound to get even more play. Cee-Lo?best known for his work with Goodie Mob and Gnarls Barkley?has a big presence on Twitter, too, even if his account isn't yet verified. Whether he's posting pictures of his adorable cat, Chocha, documenting his musical choices with the #nowplaying tag (he listens to everyone from Sly Stone to Serge Gainsbourg to Alice in Chains), or giving his take on R. Kelly's "Trapped in the Closet" saga, his tweets offer a tiny glimpse into his day-to-day life. His Twitpics of ridiculous headwear and even more ridiculous Photoshop efforts are especially worth looking out for.

Best Tweet of the Week: "Everybody say 'FUCK U CEELO!' Its the twitter u love to hate!"
Jenny Lewis
@jennylewis

Why You Should Follow: Rilo Kiley's adorable, cowboy boot-wearing frontwoman recently teamed up with her equally adorable boyfriend, Johnathan Rice, to release an album of adorable duets called I'm Having Fun Now. Now they've hit the road together for the first time, and Jenny has finally started to tweet more, posting promo videos for their opening act, Farmer Dave Scher, and links to album reviews and other Jenny & Johnny-related news (including SPIN's tour of the couple's pad). Though most of her tweets are pretty impersonal, there are moments where the real Jenny shines through?like when she apologizes to Barack and Michelle Obama, saying that they can?t come to the Jenny & Johnny show in D.C. because it's all sold out, and invites them to come to the after-party at Ben?s Chili Bowl instead.

Best Tweet of the Week: "thanks to everyone who came to our first show ever at three of clubs last night. and thanks to that dude with the cambodian rum."

While his other collaboration with a rock'n'roll lead singer?the multiple MTV VMA-nominated "Airplanes," featuring Paramore's Hayley Williams (watch here)?explored deeper emotional territory, Atlanta rapper B.o.B's track featuring Weezer's Rivers Cuomo is all party, all the time. Watch the just-released video for "Magic" below.

In the clip, B.o.B isn't quite sure if he's asleep or awake, but he does know that there's a raging house party blowing up in his crib?with hot girls dancing up a storm and eating Fruity Pebbles out of his bathroom sink.

Out on the front lawn, Cuomo and B.o.B join forces to perform for a huge crowd, with the Weezer man taking his best, whitest stab at hip-hop stage moves while signing about how every track he touches turns to gold, and how girls come snappin' at him when he hits the floor. Word!
