"Everybody that's haters, they've just been haters," Brown said in the video, which he recorded with friend and fellow rapper Bow Wow.
"All my real fans, I love y'all," Brown said in the May 26 clip. "I ain't a monster."
Brown hasn't spoken out about the Feb. 8 incident with singer Rihanna since he was hauled into court in Los Angeles and pleaded not guilty to assault charges.
The couple reportedly got into a fight over a text message Brown received from another woman.
Brown and Rihanna tried to make it work after the incident, which left her with a black eye and swollen lip -- but the pair hasn't been spotted together in several months.
Brown, who shot to fame with his R&B hit "Run It," also pitched his new album, "Graffiti," in the YouTube video, saying he expects to drop a new single this summer.
"Be ready for it," Brown said. "We ain't going nowhere."
