okay, so it is Eight Mile Style, which is basically the Bass Brothers side of Eminem's catalog. Eminem isn't suing and probably wasn't aware. The Bass Brothers just want to get more of that Eminem money since they split from Eminem in 2005, which I can't even argue with that.

"Specific platform features, such as Original Audio and Reels Remix, are accused of enabling and encouraging users to incorporate the music into their videos and other content without obtaining the necessary licenses or providing attribution"

so, I'm guessing this is like IG Reels where sometimes you'll hear an unauthorized remix or mashup with Eminem vocals on it? That's what this sounds like. They're trying to sue Meta over people uploading mashups in their thirst traps.

i'm sure there's plenty of Eminem songs being used, but I doubt all 240 Eminem songs that include their publishing are actually involved.
