Jamal Grinnage and Eric Murray -- that's Lil' Fame and Billy Danze -- want to put the kill switch on Cena's song, "Time Is Now," saying it borrows heavily from their hit "Ante Up." In a federal lawsuit, they claim WWE's lawyers actually found some person to sign off on the license who was only a receptionist and didn't have authority to do so.

The biggest point of actual musical contention is one non-English line -- "BRRR Abado" -- that appears in the original song once, and in JC's song three times.

The suit asks for destruction of Cena's song and $150K from the defendants. No word from Cena or WWE yet.
