Who is Madison Acid

Ik its dumb but i have a thought that its Trung why: 1.Maddie dont have much songs her first song was after Trung left 2.In Maddie in Heaven maddie says "Freestyl like we used to" 3.In sweaters where trung sings theres a sample from song by MC Lyte and Maddie sampled her for example in Kamikazee and probably more Idk if it makes any sense
