Radio stations in American cities like Chicago, Los Angeles, Tampa, Pittsburgh, and New York City have begun playing a song being toted as “The Official Chris Brown Diss Track,” The Associated Press reports.

Chris Brown, 19, has been charged with felony assault and making criminal threat after he allegedly beat his girlfriend, pop star Rihanna, on the morning of the 2009 Grammy Awards.

The techo-inspired track is called “My Flow So Tight” and was recorded by an up and coming Chicago-based group called Smoke Jumpers.

It features the repeated line: “Chris Brown should get his ass kicked.”

HA!
