 |  | | The incomparable Mariah Carey made history this month when she passed Elvis as the solo artist with the most number-one singles in the modern era. The party, however, is just getting started, as iTunes is the place-to-be in celebration of her new release, E=MC2. In addition to her new album, Mariah programmed the iTunes Pop genre page with her favorite videos and collaborations. And be sure to browse through her celebrity playlist and catalog sale. | |  |  |  |   |  |  |  | Idol Gives Back
 In addition to witnessing breathtaking performances by stars such as Mariah Carey, Carrie Underwood, and Snoop Dogg, the Idol Gives Back television special illustrated how easily we can help those in need. And through iTunes, you can aid young people across the globe by purchasing the evening's performances, including Fergie with John Legend, Annie Lennox, Miley Cyrus, and, of course, the Top 8 American Idol finalists. Net proceeds from your purchases will go to the Idol Gives Back Foundation. |  | |  |  |  |  |   |  |  |  | The Black Crowes
 The Black Crowes stepped into the world of rock 'n' roll as outsiders with their 1990 debut, but by the time they released their latest effort, Warpaint, last month, Chris Robinson and company were living legends of hard rock. To get a taste of everything in between then and now, take a listen to their exclusive iTunes Originals session, containing new versions of old favorites and loads of interviews. |  | |  |  |  |  |   |  |  |  | Juno
