Rayvanny's announcement comes a few months after fans noticed some changes on his Instagram bio and speculated that he had ditched the label.
Previously, his bio read, 'From East Africa Tz, BET Awards winner, signed under WCB Wasafi,' followed by links to his current music.
Since April this year, Rayvanny's bio changed to; 'CEO NLM Music', tags of his company, 'Next Level Music' and a BET Award winner.
Rayvanny started his label last year and issued a statement saying he would continue working with Wasafi.
In January this year, fresh reports came that Rayvanny was asked to part with TSh2 billion (Sh98 million) if he was in a rush to quit the label that created his musical fame.
Personality Mwijaku, in an interview, said Rayvanny was asked to pay the sum but was unable to.
"From the information I got, recently Rayvanny got a partner from Zambia who wanted to invest in his Next Level record label," he said.
"But the investor insisted that he has to be independent to avoid collision, and that means ditching Wasafi. When he presented the case to Wasafi management, the managers there presented him with an invoice of TSh2 billion."
