If purple or violet is your favorite color, you have a deep need for emotional security and to create order and perfection in all areas of your life, including your spiritual life. You also have a deep need to initiate and participate in humanitarian projects, helping others in need.
Some apps store their save games/configuration data files on /sdcard/APPNAME/ , or just on the /sdcard/. To be able to use root apps, you'll need to have rooted your Android device and have given permission from one of the superuser apps.
/data/data/com.google.android.music/files/music. 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).
