Looking at Bilangilangi's YouTube channel, all the top 5 hits -- Ratata, Magazine, Ntya (featuring Winnie Nwagi) and Number Embu, apart from Nalinda -- which was produced by Andre -- all were produced by Nessim Pan Production.
Nessim, while speaking to Galaxy FM, said Zex Bilangilangi, real name Tadeo Mayega, is very talkative and full of humour so it's very hard to concentrate around him.
"He is too good" at holding conversations, he said, laughing.
Nessim's most recent song with Zex is Ntya, which was released four months ago, and is a hit. Bilangilangi has also worked with Artin Pro.
Who is Nessim?
One of the most prolific producers, Nessim started his production journey under the mentorship of Tony Houls Bikumbi, who was at Fire Recordz, which is owned by Bobi Wine.
In between leaving school and joining Fire Recordz, he also did karaoke and worked as a salesman for music CDs.
While at Firebase, he featured in lots of Bobi Wine music videos.
Then Nubian Li, who was dating Feffe Bussi's sister, connected the two. Bussi and Nessim teamed up to do a Luganda version of Vybz Kartel's Summertime.
He then left Firebase to join Badi Muzik Production, which was owned by Bashir Lukyamuzi. At the time, Lukyamuzi, alias Producer Badi, used to travel to Dubai a lot so it gave Nessim a lot of studio time.
Nessim was introduced to Lukyamuzi by Big Chief.
At Badi Muzik, Nessim met A Pass who was also still a budding singer. A Pass was already connected to some singers, so he brought some like Aziz Azion and Eddy Kenzo but they didn't like the beats.
Eventually, Don MC Kapata came and they made Oli Mbuzi and Nessim got a breakthrough.
While at Fire Recordz, he had worked with Serena Bata and Lydia Jazmine who was still a student.
So, when Rabadaba came to record Love Portion, Nessim convinced him to collab with Jazmine on You Know, which also played a critical role in launching her music career.
Then Mowzey Radio came to his studio and they worked on Ntunga, the Goodlyfe song that fully launched Nessim's music production career.
Speaking to Galaxy TV, Nessim said he had given the beat for that song to Serena Bata and Nince Henry but they rejected it.
"When Radio sang to the beat, he said thing song is going to make you big," said Nessim.
Then in 2017, he and A Pass left Badi Muzik to start their own studios.
That same year he lost his mother and he said this was a big turning point. Nessim, currently 28, said he decided to work hard and retire at 35.
He has been in the industry for over 12 years.
