Jay Z nominated for best rap album Grammy

Jay Z picked up nominations across nine categories in the pop and rap categories, including best pop duo performance for "Suit & Tie" with Justin Timberlake, and best rap album for his July release, "Magna Carta...Holy Grail."

But the 44-year-old Brooklyn, New York-born rapper failed to land solo nominations in the top Grammy categories for record, song and album of the year, scoring only one as a producer on Lamar's "Good Kid, M.A.A.D City" record, nominated in the album of the year category.

Lamar's album will face off against Sara Barielles' "The Blessed Unrest," French electro-dance duo Daft Punk's "Random Access Memories," Taylor Swift's "Red" and Macklemore & Ryan Lewis' "The Heist" for album of the year.

Timberlake and Jessie J headline at iTunes Festival

Headline acts for this year's iTunes Festival are to include Justin Timberlake, Jessie J and Queens of the Stone Age.

The free series of events will include more than 60 acts to be performed throughout September at London's Roundhouse.

Also on the bill, as the first batch of names was released today, are Primal Scream, Thirty Seconds To Mars and Jake Bugg.

Jessie J axed a tour earlier this year because she did not want to play the sell-out shows before the release of her album, which had been delayed.

Apple executive Eddy Cue said: "This year's iTunes Festival is the best ever with an incredible lineup of global superstars and stellar emerging artists. We're honoured so many renowned artists are part of this year's lineup."
