The song is well structured, has nice beats, and is set to be a major hit in the region, thanks to the excellent reception it received.

What's more, Harmonize managed to drag Diamond Platnumz's baby mama, Ugandan socialite cum business woman Zari Hassan, into the song.

In the song, Harmonize claims Zari is losing weight due to Diamond, who is also known as Chibu Dangote.

Diamond and Zari parted ways last year following accusations of unfaithfulness among them.

"Diamond Platnumz's 'Uno' is making Zari lose weight. (Uno la Chibu Chibu linamkondesha Zari)," read part of the lyrics.

Meanwhile, Harmonize parted ways with Diamond's Wasafi Classic Baby (WCB), and is now under new management.

He has managed to release several songs after ditching the WCB record label.

He is one of the most successful and followed musicians in Tanzania and the entire East African region.

His talent and high quality music has endeared him to Kenyans who form a huge percentage of his fans in the region.
