If you go into the metronome playback settings, there is a toggle to "Keep metronome playing after switching songs". If you enable this, you don't need to enable the auto-start setting for each individual song. However, you do need to assign the metronome tempo you want for each song. MobileSheets is not going to support a mode where the metronome will keep laying the previous song's metronome tempo while viewing a different song. That would not be intuitive and would be very confusing to users, as why would they want a different metronome tempo than what the current song requires? 

I do not currently provide a way to apply a metronome tempo to every song in the current setlist, but I do plan on adding that once I have some bandwidth.
