Request: absolutely ONLY allow cached/downloaded music and NEVER cellular data

Apparently, when filtering for “cached music” only is still sometimes streams music when I’m on cellular data (I posted a bug report). I would like an option to never play music when not on wifi.

Perhaps in the “playback settings / celluar bitrate” have a option for “none/never” - I currently have it set to 64 to minimize the damage to my cellular data.
