No iTunes install for Linux ?

I just have recently got myself a Raspberry pi zero, and wised to see if there was a Linux version of iTunes.. I don't see any, there is only Windows and Mac. I was hoping I would use it to stream my iTunes library from one of my Macbooks through the Raspberry pi, while i practice on some code, because I have decent sound system on the HDMI screen/TV, which is currently connected to my main Macbook when I am at home, but when i use the Pi, my macbook just uses its laptop display lid. I do hope Apple makes a Linux version of iTunes soon, because since windows 8, Windows has become a piece of software junk, only worth running games on, than doing productivity which the Mac does best.
