The national organiser of Operation Dudula, Nico Dumakude, will march to the SABC on May 8.
Nico claimed the Ukhozi FM music department and its music compilers are corrupt.
"Ukhozi FM is suppressing our music and rejecting it while making deals with big record label bosses from Kwa Zulu-Natal. They bribe them by booking them as MCs, and let them be DJs at Ukhozi FM events", he alleged.
When TshisaLIVE asked Nico if he has submitted his music to Ukhozi FM, he said: "They played my songs on the station before without any hassles, but suddenly in 2018 they started rejecting my music.
"The SABC is captured by a well-known DJ from Kwa Zulu-Natal who makes songs which are rubbish. The picket lines are ready and I call all artists who have grievances to join us in dealing with this station once and for all."
SABC head of communications Mmoni Ngubane said: "The SABC can confirm it has not received a memorandum and has not been informed formally of the planned march and therefore cannot comment on issues it has not been made aware of. The SABC is a national key point area and security protocol will be observed accordingly should there be any such action. Ukhozi FM has released its line-up for 2025/26 and all information in terms of programmes and presenters has been provided".
