My guy, he and his friends constantly pronounce their names for you in their songs.
I call him R.Z.A not Riza cause that ain't how that shit is written.
I know rza is wholly unaffected by your pronunciation of his name, but I implore you to rethink this behavior with people actually in your life.
Pronounce other peoples names the way THEY want you to, anything else is just narcissistic.
