The "Loyal" performer picked up one GRAMMY in the past, for Best R&B Album in 2012, and was nominated this year for Best Rap/Sung Collaboration for "Only," with Nicki Minaj, Drake and Lil Wayne.
Brown concluded his diatribe by saying he was "thankful" for his fans.
"I am able to be the best artist I can without having to conform to the ways of my peers. I also need my commission," he wrote. "A lot of y'all favorites are my Children!"
#GRAMMY? This is probably the main reason i love being free to create any kind of music I want. Too many people kiss ass And work less
Following the GRAMMYs rant, Brown decided to weigh in on Joseph Fiennes' casting as Michael Jackson in a British TV movie based on an urban legend about the king of pop and Elizabeth Taylor.
"Y'all know y'all dead wrong to have dude play MJ. If that's the case LET ME BE SUPERMAN. Da f**k they do that at? Is that blackface?" he tweeted. "I DONT SUPPORT THAT CORNY ASS S**T!"
Fiennes commented on the controversial casting exclusively to ET, saying, "I'm as shocked as you may be." That said, the BAFTA nominee added, "He was probably closer to my color than his original color."
