Accessing Google Play Music?

Hi everyone,

I haven't found any recourse on this topic. Since MP3s are pretty much antiquated on mobile phones, I need my Android app to pull steaming music in. I know I will need to have the user sign into Google services but I'm not even sure if this is possible in Unity. Has anyone been able to access Google Play Music library through Unity? I'm not sure where to begin. I will likely need to access ShouCast, SoundCloud, and all the others as well, but for now Google Play Music is my primary target. Im using Unity 5 personal/indi (the free one).
