Wu members often recite written verses when asked to freestyle during radio station interviews. They'll dust off material from 36 Chambers or Forever, stuff we all grew up on, so I have a hard time believing they think no notices.
Maybe they figure freestyling is beneath them, which I'll go along with. Up-and-comers have to perform well in that setting to get noticed. But royalty? They don't need our attention.
They've had it for 17 years.
