Music & Society
Petersen's reaction of politicians was not entirely unexpected. Pressure also came from some church leaders that took great exception to Munyaule, a song that out-rightly euphemised sex like no other musician has ever done in Zambia. Petersen used the visibility Munyaule had brought him to highlight several injustices he saw in Zambian politics and the society it breeds. Petersen did not spare the church with a background in the church, Zagaze recounts in his song Amakwebo Mu Church, the travesty that seem to have engulfed the Zambian church. In his song Amakwebo Mu Church Petersen visits a church after a long time only to find that the church has now become a market place, selling everything from houses, to cars, and music albums. He then requests, that “Messiah bwelelanso ukwapule nafuti … ama kwebo mu church yafula" which means Messiah come back on earth and come Whip again.... Cause business activity has increased in the church. The message in Amakwebo Mu Church is quite appropriate for the Zambian church, particularly the Pentecostal church that seem to be experiencing a serious identity crisis.
Music & Politics
Petersen's prolific criticism to the politicians that had moved to ban his 2005 Munyaule. In the Job 13:13 song Zagaze stated that the parliamentarians had better things to do in parliament than debate his songs. Calling politicians as “ba mwankole wearing black suits”, he called out their hypocrisy about targeting his Munyaule songs when they themselves had absolutely no morals. The same politicians who were pontificating about morals were “corrupt thieves, selfish and wife batterers.” In 2013, he featured in PilAto's single entitled BUFI a highly politically charged song that labeled the late PresidentMichael Sata a ‘Father of Lies’. The song got a negative feed back from the supporters of the ruling party.
