TMZ has learned that Three 6 Mafia are being sued for "over 150 independent acts of copyright infringement from more than 100 individual sound recordings."

A group of artists from Memphis claim to have collaborated with Juicy J, DJ Paul, among others as they were trying to make a name for themselves in the 1990s. The suit alleges that their contributions to Three 6 Mafia included producing, recording, and writing lyrics. "M.E.M.P.H.I.S." and "Tear Da Club" are cited as examples where these acts weren't credited for their help writing the lyrics.

In September, DJ Paul and Travis Scott came to an agreement on a "tentative settlement" in a copyright infringement lawsuit over the song "No Bystanders" off the 2018 album Astroworld. In his suit, Paul accused Scott of heavily borrowing from the hook on "Tear Da Club," which he claims to have written. He said La Flame was never granted permission to use a portion of their track, and was seeking $20 million at the time. Both sides ended up settling on an undisclosed dollar amount. 

Three years ago, pioneer Three 6 Mafia member Gangsta Boo created waves when she called today's rappers for stealing old songs from the group. While she didn't specify who she was talking about, people jumped to their own conclusions and theories. 

The group of Memphis-based artists are looking for unspecified damages, as well as an injunction which will prevent Three 6 from profiting any further from what they consider to also be their work.
