1. Bono: As if he weren’t rich enough, with the Facebook IPO, the U2 frontman becomes a billionaire, and the world's richest musician. If he still hasn’t found what he’s looking for, we’re sure he can buy it now.

2. Taylor Swift: Swifty donates $4 million to the Country Music Hall of Fame, the largest ever by an artist. In perhaps a  sign of the times, Eonline.com’s headline about the generous gift?: “Taylor Swift Grabs Dinner with Dianna Agron, Donates $4 Million to Country Music Hall of Fame.” If she had made the donation in a bikini would that have been enough to top Agron?

3. Jay-Z: As if being a new dad weren’t enough, he gives birth to his own event, the Budweiser Made In America festival, to be held over, appropriately enough, Labor Day.

4).Britney Spears: She confirmed her position as a judge for “The X Factor” for a reportedly $15 million. Simon Cowell continues to go after the youth audience by also enlisting teenager Demi Lovato, who’s not a girl, not yet a woman.

5. One Direction: The British band is about to start on its sold-out summer tour in the U.S. Also sold out? The group’s US summer tour is already sold out and the band just sold out a dozen shows at London’s 02 Arena.The only direction this boy band knows is up.

6. String Cheese Incident: The jam band, who is feuding with TicketMaster, gave 50 fans (presumably very trusted ones) $20,000 to buy tickets , which the band will now sale through its website at face value so fans don’t have to turn to scalpers. That’s how you have a loyal following without ever having a huge radio audience.

7. American Idol: For all the word about the show losing its prominence, it’s about to have back-to-back No. 1s on the Billboard 200 as Adam Lambert’s “Trespassing” gets ready to take the place of Carrie Underwood’s “Blown Away” on the Billboard 200.

8. Amanda Palmer: We were raving about her a few weeks ago when she’d raised nearly $400,000 through Kickstarter, now she’s passed $750,000.  That’s quite the recording budget...or the equivalent of what Dr. Dre has spent per month on "Detox." 

9. Justin Bieber:
The teen titan invests in Spotify. Is he the next Sean Parker?

10. Donna Summer:
She took her last dance on May 17, but her music will live on forever.
