Speaking in a recent digital forum, Diamond said most of his fans in Tanzania bash him after he does English songs since they do not understand the language.
"Doing English songs is the only way I could help Rayvanny to go international," he said, adding that Rayvanny was afraid at first.
"If you do not go international, your fans say you are not working hard, yet they do not want you to do English songs. Our fans praise us when we keep doing Swahili songs," he said, adding that he will continue pushing until he conquers international platforms.
Diamond said artistes should consider that they are writing songs for people who do not understand Swahili.
"We are currently pushing international and it is not easy," he said.
"You have to have a big fan base from Africa so that you can conquer there. There are other platforms that are not making money for us and so we have to keep pushing."
Diamond's message comes a few days after his signee's show in Houston failed.
Reports indicate that very few people turned up for the show.
Diamond said most West African countries support artistes.
In the forum, Diamond also asked his fans to support his music in platforms he can earn from.
"We earn through our music. Digital music is currently making good money. We used to earn through shows, but now we earn through digital," he said.
"Stop supporting us on some social media, support us in the platforms where we can earn from. They think we are doing well by comparing ourselves on such forums, but in the real sense, we are not earning from such platforms."
Diamond also said fans should move from the aspect of comparing artistes.
"Who doesn't know Harmonize and Alikiba are big artistes?" he said. "As artistes, we are surrounded by our families, friends, but they are the people to show us how to move forward," he said.
He said the reason he does not read comments on social media is since he does not want to attack his haters.
