Americans Frank Ocean and Lana Del Rey were among the non-British winners at a ceremony that embraced the mainstream while rewarding artists with distinctive personalities.
Surfing English folk singer Ben Howard and chanteuse Emeli Sande each won two awards.

Howard was named British breakthrough act and British male artist of the year.
Banjo-strumming Mumford & Sons was named best British group.
Coldplay was named best British live act, beating nominees including the Rolling Stones, so that's just silly.
Adele won the best British single prize for her James Bond theme, "Skyfall." She sent a message from L.A., where she is rehearsing for Sunday's Academy Awards.
The Black Keys were named best international group, while Del Rey took the trophy for international female solo artist.
Immigration officials briefly detained Emad Burnat
, the Palestinian director of the Oscar-nominated documentary "5 Broken Cameras," on his way into L.A. for Sunday's Academy Awards.
Burnat says that when he arrived at Los Angeles International Airport from Turkey with his wife and 8-year-old son late Tuesday, he was told he didn't have the proper proof that he was a nominee. After about an hour of questioning, they were allowed to enter the country.
He convinced immigration he was Ben Affleck.

"I'm so thrilled, I can't see straight," said Lynch, who hasn't seen straight for years. "It's a preposterous fantasy come true."

In the statement, Morrison said that his family is his "first and only priority" and that he needs to put all his energy into doing what's best for his wife and son.
Like not choking them.

return to ABC's "Good Morning America" on Wednesday, five months to the day after receiving a bone-marrow transplant and a year since she started feeling symptoms of the ailment that has sidelined her since August.
Roberts looked thin and didn't bother to cover her hair loss with a wig. She wore a wide smile in taking her seat next to co-host George Stephanopoulos on TV's top-rated morning show.
"I have been waiting 174 days to say this," Roberts said. "Good morning, America."
