Where does Google Play Music v5 store music locally? I know this question has been answered for older versions of the app, but where does the most recent app store offline music?

Clearly the mp3's I've selected are downloaded - because they play without an internet connection. But the default location for offline music is empty. 

Any ideas guys?
My Google Music 5.3.1317M.940995 running on a Nexus 4 with CM11 stores the mp3 files under


  /data/data/com.google.android.music/files/music


You need root to access that directory.

A older version of Google Music on a Galaxy S stored it on the SD card. And, as I read in the official changelog, Google Music 5.x seems to be able to use the SD card as storage too. Which makes sense for devices with low internal storage space (/data/data).
