New Chris Brown music has been popping up on the Web — and the singer is not happy about it.

The 19-year-old is frustrated that fans have been listening to a song called Electric Guitar that’s supposed to be off his third album, due out next year.

“I’m mad that it’s leaked,” he told The Associated Press in a recent interview. “The record’s not finished. It’s supposed to be me and Rihanna’s duet.”

Electric Guitar would be yet another collaboration between Brown and his rumored girlfriend. He appeared on a remix to her smash hit Umbrella last year, and he’s listed as a co-writer on her latest No. 1 hit, the dance song Disturbia.

“It’s fun being creative and even if you have a concept in your head to write about, you can write it and give it to someone else because it might not personally fit you, but it might be an idea you have,” said Brown. “So with (Rihanna) that was an idea I had. I just wanted to go totally left and kind of weird, and that’s what I threw at her.”

Brown is still riding high off the success of his second album, Exclusive, released last year. It was rereleased in June with new material, including the song Forever, which is now No. 2 on the chart, a notch below Rihanna.

“Having the support of my fans on the second round was just incredible, and it’s even getting bigger now,” he said of his success.

He also said he’s working on a new reality show about break-dancing: “We’re going to do our thing and have a lot of fun.”
