Black Sabbath perform on "CSI" (Photo: CBS)By Jon Wiederhorn

For weeks now, the Black Sabbath promotions department has been reminding fans and the press that the season finale of "CSI" would include a snippet of a song from Black Sabbath’s new album, 13, which comes out June 11.

On Wednesday, Universal Republic Records made good on their word, and fans didn't even have to wait long to see the heavy metal legends in action — or at least lip-syncing the new song. Viewers who tuned in late, figuring Sabbath would be saved for the end of the show, missed the whole thing.

Slayer has announced that there will be a public memorial to commemorate the band's late guitarist Jeff Hanneman on May 23. It'll take place at Los Angeles's Hollywood Palladium from 3:30 to 7:30 p.m. Fans are encouraged to attend, and will be admitted on a first come, first-in basis until the venue is full.

The Jeff Hanneman Memorial Celebration will be an opportunity for Hanneman’s family, friends, and fans to reflect over the guitarist’s colorful personality and considerable musical accomplishments.

Dropkick Murphys (Photo: Chelsea Lauren)Like most Americans, the members of the Dropkick Murphys were shaken when their hometown was attacked at the Boston Marathon finish line in April. Now they've done something about it.

The band has just released Rose Tattoo: For Boston Charity EP, which includes a new recording of the title track featuring Bruce Springsteen; as well as two other songs, "Don't Tear Us Apart" and "Jimmy Collins's Wake." Performed acoustically, those two tracks were recorded live at a gig at the Gibson Showroom in Las Vegas, just four days after the bombings.

Kanye performing in NYC (Photo: Theo Wargo)Leave it to Kanye West to turn an embarrassing moment into a massive onstage tirade. The rap star, who performed at a surprise show at New York's Roseland Ballroom Wednesday night for an Adult Swim Upfront party, took the opportunity to lambast paparazzi and tell the world that he "ain't no motherf---ing celebrity."

During his hour-plus set, West went on a rant for more than three minutes, declaring himself the "worst kinda celebrity" and saying he was fed up with people running up to him with cameras, asking him "dumbass questions, throwing me off my focus and sh-t."

It's likely that a recent incident in which West walked head first into a "Wrong Way" sign when paparazzi were following him and his lady love, Kim Kardashian, in Los Angeles, sparked the tirade.

Wade Robson (Photo: Denise Truscello)While the Jackson family's wrongful death lawsuit against AEG Live continues in a downtown Los Angeles courtroom, another Jackson-related drama is playing out.

Dancer/choreographer Wade Robson filed suit against the Michael Jackson estate last week, alleging that Jackson sexually abused him from age seven through 14. This morning he appeared on the "Today" show — and in a bombshell interview with host Matt Lauer, spilled the beans on his relationship with Jackson and explained why he waited until now to come forward with the allegations.

Frank Ocean (Photo: Jamie McCarthy)If you're tired of the same-old, same-old awards shows--best this, best that, yawn- the O Music Awards are coming back again this year to shake things up. MTV, VH1, and CMT's fourth annual show celebrating music, technology and fan influence will feature its usual round of unorthodox categories, with Beck and Frank Ocean leading the pack of nominees.

Beck and Ocean have two nods each. Other artists nominated include Justin Bieber, Demi Lovato, Miranda Lambert, Pussy Riot, Ed Sheeran, David Bowie, Macklemore and Ryan Lewis, and Tyler, the Creator.

Of course, the awards categories themselves at this particular show are of as much interest as the colorful list nominees themselves. Returning categories this year include Digital Genius Award, Fan Army FTW, Best Web-Born Artist, Must Follow Artist on Twitter, Best Music App, Best Artist Instagram…and the fetchingly titled Too Much Ass for TV .

"I do whatever I want," Beyoncé belted on stage in Belgium Wednesday night, referencing a lyric from her new single "Grown Woman."

And she means it. Doctors had the superstar cancel a Tuesday concert in Antwerp to treat exhaustion and dehydration, and also advised that she cancel Wednesday's show. She refused.

"Now, my doctors told me not to perform tonight, but there was no way in the world. I just have to say that y'all give me so much inspiration," she told ticket holders inside Antwerp's Sportpaleis.

Hip-hop and basketball go together like peanut butter and jelly. Playing a hot jam over the P.A. is a great way to hype up the crowd and it's incredible exposure for an artist, especially if the game is televised nationally.

Macklemore, however, isn't too happy that the Oklahoma City Thunder has been using "Can't Hold Us," his song with Ryan Lewis, to get the crowd going during their home games.
