Q: How can I shuffle my library?

I'm using an Galaxy S3 (although I don't think phone model makes a difference) and for the life of me I don't know how to play or shuffle my entire library. On iOS I can do it by voice (with Siri) or from the app, but the Android version seems to be missing this functionality. This alone makes the Android version almost useless to me because I normally shuffle my entire library and I can't do it unless I add my entire library to a playlist which is a pain in the ***.

Any suggestions?
