1. Adam Yauch: RIP MCA.

2. Amanda Palmer:
The former Dresden Doll raises more than $400,000 on Kickstarter for her next album. That’s kick ass.  

3. Jack White:  One is not the loneliest number: White scores his first No. 1 on the Billboard 200 as a solo artist: a feat he never reached as half of the White Stripes.

4. Michael Jackson:
Pepsi deal will result in his image in on more than 1 billion Pepsi cans in the, perhaps oddly, titled “Live for Now” campaign.

5. Skylar Laine:
Another favorite leaves “American Idol” earlier than expected. She’ll be back on a record label near you soon.

6. Dave Grohl:
Add director to the Foo Fighter’s resume: He’s behind a new documentary on Sound City, the Los Angeles’ studio where, among others, Nirvana’s “Nevermind” was recorded.

7. The Grammys: A New York judge dismissed a suit filed by a Latin jazz musician who alleged that the cutting out 31 categories hurt artists’ earning power.

8. Carly Rae Jepsen
: Justin Bieber’s buddy scores her first top 5 hit with “Call Me Maybe.” As the tattoo on the hot dude in the video (viewed 47 million times) states, “The sky’s the limit.”

9. Justin Bieber:
Sure, his video for “Boyfriend” finally debuted, but it’s his “Most Viral Video Ever”  for Ryan Seacrest that deserves the attention: Puppies plus sneezing babies = total win.

10. Casper Smart: Jennifer Lopez’s boyfriend lands the job of choreographing her new tour. Nice perk of dating the boss.
