Mayor Jose Neto of Sao Lourenco in southeastern Minas Gerais state told Globo television he was banning songs that incite violence and disrespect authority and wanted to protect more traditional Carnival music, such as samba.

Anyone caught listening to funk -- a pounding beat often with sexual lyrics popular in Rio de Janeiro's slums -- or rap during the Carnival period would have to turn it off or face arrest and up to six months in prison, he reportedly said.

"They are mass gatherings that demand better coordination, control and security that a public festival like Carnival doesn't allow us to adopt," Neto told Globo TV.
