When I was riding my bike a few days ago I forgot to turn on my music so I used the OK Google command to turn on my music and worked fine. Now later during the ride a song came on that I did not know was on my phone but I didn't think much of it. later in the evening when I was going home again I grabbed my phone to play music again and I saw the "Downloaded Only" tab was disabled (I always have this on including stream only using WiFi). This made me think of something. So i turned it back on and kept my screen awake to see what would happen. I use the command and sure enough it disables the downloads only setting and starts playing online content.

PLEASE GOOGLE disable this because I only have a 1Gb data cap and it's a nice feature to have/use but if it keeps playing online songs I can not use this.

If any redditors have a workaround for this or a mod please tell me. (phone is rooted)
