Tanzanian Artist Harmonize has criticized Diamond Platnumz for constantly taking credit for his success, stating that it is becoming irritating. 

"Nilimtoa!!!!! Nilimtoa!!!!!Ndio!! Kweli!! Asante!! Ila Inachosha!! Nakalibia Kujuta??"

Diamond Platnumz defended himself on Instagram, expressing admiration for Harmonize's accomplishments and suggesting a joint concert. 

"Konde, Acha Nijivunie Nyie Ndio Wanangu Wa Dhahabu, Nikitoka Hapo Nahamia Kwa Wajukuu Zangu Sasa Kina Ibra, Mac Voice Етс... Kwenye 15 Years Nataka Tufanye Event Moja Ya Ukoo Mzima And We Celebrate Kidogo Mungu Alichotubariki"

However, Harmonize turned down the proposal, stating that Diamond Platnumz would not be able to afford his current booking fee of TSH 600 million /Ksh 30 million per show.

"Tatizo Masikini Huyu Hukumbuka Wanawe Akishakusanya Mali Zake !!!!! Anyway Haiwezi Kuja Tokea!!! Hiyo Miaka 15 Maana Milllioni 600.m Kunilipa Hutoweza!!!
