Behind the Lyrics keeps turning back on

[Dearmissally]

Hi,

I have a Samsung phone (s7 maybe?) and I use data to listen to Spotify on my way home from work. I tried "Behind the Lyrics" at work on wifi and found that I never ended up looking at it so I turned the feature back off (the switch in settings is grey and to the left). Its happened a few times where it will randomly turn itself back on and when I walk home, 12mb+ is used instead of my usual 3mb or so. I only have 500mb per month so this is a huge deal for me.

How the heck do I disable it and prevent it from turning back on??
