I tried your solution. I got all the way thru an album until the very last song. So, about the same time without the issue as when I went in and manually disabled everything. I feel like the issue could be very easily resolved if the pure music mode supported a third party like Tidal. So, essentially just have a general setting to be able to dedicate all cpu to whichever music player you want as opposed to only working with the fiio music app.
