Being a fan of old kungfu movies, I chose monk as my main job and wanted a philosopher name to suit it. Zarathustra was both a philosopher and a monk. I studied him a few months prior and liked his principles. I used to get alot of random tells but not so much now...
Thus spoke/spake/sprach Zarathustra!
Thus you spoke!
etc...
...so "Zarathustra" is a musical piece [see Ric Flair: WCW theme (Richard Strauss, Also Sprach Zarathustra)], a middle eastern philosopher [Zoroaster of Zoroastrianism], and that famous text [Nietzsche].
