Once you start getting a bit of a success and fame, the lawsuits start piling in. DJ Mustard is starting to reach that stage in his career, with a new lawsuit claiming he ripped off ideas from a friend by the name of Mike Free.

Mike Free claims to be a childhood friend of Mustard in his new lawsuit, and states that he wrote, composed and produced the song that became the launching pad for Mustard's career-- Tyga's "Rack City." However, he says he never got his deserved credit for it. This wasn't a one-off song, Mike Free says he and Mustard agreed to share composer and producer credits, as Free had all the ideas and Mustard had the necessary connections in the industry. Free says he had ideas for several other big Mustard tracks-- "Don't Tell Em" by Jeremih, 2 Chainz's "I'm Different," Big Sean's "IDFWU," and more.

He wants royalties from all those songs, plus proper production credits.
