Billboard Magazine -- the bible of the record biz -- has named 18 year-old Chris Brown the top artist of 2008. He had previously won the honor in 2006.
"It's bigger than what I can ever imagine," he enthused. "It's unexpected totally, so it's a surprise."
The artist's hits this year include With You and Forever, along with duets like No Air with Jordin Sparks. Last month, he snagged 3 awards at the American Music Awards, among them artist of the year.
The Billboard title is awarded based on sales, downloads, airplay, and other factors. The No. 2 artist was Lil Wayne, followed by Rihanna, Alicia Keys and Taylor Swift.
